Why are mountain roads always designed as winding mountain roads?

Vehicles on steep mountain roads cannot go straight up and down, and can only use detours to reduce the slope, so that no matter how high the mountain road cars are, they can go up and down. The nature of the winding mountain road is sloped.

The advantage of deformation is that the car can save effort, and you can drive up the towering cloud peak along the winding mountain road.

The winding mountain road is tortuous, and the main purpose is to increase the slope length and save more effort.

<> around the mountain road to repair the twists and turns because the mountain is steep, in order to reduce the difficulty of climbing, the running vehicle is to reduce the upward resistance, so according to the direction of the landform, choose the terrain suitable for the road, according to the strength of the vehicle climbing, moderately reduce the slope to build a road suitable for walking vehicles, moderately reduce the upward resistance of the vehicle, therefore, the mountain road built just presents a twist and turn.

China is a mountainous country, the area of mountains, hills and land plots accounts for 69% of the total land area of the country, and most of the sections of national and provincial roads, county roads and township roads built in the early days are winding mountain roads, in the southwest and central regions.

The winding mountain road is still the main body. Mountain roads are roads for the benefit of the people in the mountainous areas, and the people in the mountainous areas must have roads open to traffic if they want to contact the outside world, and they must formulate policy routes according to local conditions and the actual situation, and the cost is not high. Where the plan is feasible, choose a tortuous path.

Generally speaking, this beautiful landscape is not visible in the plains. We can drive and experience it when we have time. Because the road is tortuous, going up the mountain, this is called a zigzag mountain road, and you can't build so many twists and turns just because it is called a zigzag mountain road.

Road construction should be based on the actual terrain and safety as the first standard. No one wants to make the road so crooked.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

In this way, it is safer, the mountain road is originally rugged, and the mountain road is designed as a winding upward road, which can reduce the difficulty of climbing, and the road will be built according to the local terrain, and then built as a unified standard. When driving on a winding road, be sure to pay attention to safety.

Because the winding mountain road will be safer, it will save the driver time and effort when getting on the bus.

Because it is safe to do so, it can conform to the terrain. Roads will be used for a longer time.

The layout and form of the route can be basically determined when selecting and setting the route of the mountain road. The mountainous area is characterized by the undulating terrain, frequent terrain obstacles and unfavorable factors, and the influence of climate, especially rainfall, is prominent, so it is necessary to determine various control points that have the effect of controlling and influencing the elevation, such as the starting point of the planned route, the cross-ridge pass, the deep excavation high fill site, the tunnel entrance and exit, and the vicinity of the river. The designer places these points on the topographic map.

After being marked up, they play a role in controlling the general direction of the route, hence the name control points. In order to overcome the height difference, it is necessary to use the method of spreading the line (extending the route mileage to overcome a certain height difference with a certain slope). It can be spread out naturally, that is, by taking advantage of the natural terrain, for example, the line can be protruded around the mouth of the mountain, can be laid along the valley in the concave, and can also be set along the ridgeline when the situation is favorable.

Although the ridge line is conducive to drainage and reducing the amount of work, if the terrain is too high, the ridgeline can easily cause the construction and maintenance of the supply service to keep up, in fact, it is not cost-effective. For mountainous areas with poor terrain, the way of turning back is more common, which refers to the way of returning to the original slope by turning an angle of approximately 180 degrees due to the unfavorable terrain when the line is spread on a certain hillside.

Winding mountains. Highway is a common type of mountain road, and its main feature is that it is built around the mountain and relying on the hillside, with steep slopes and sharp bends and undulating slopes. When the vehicle travels two road sections of the same height, if the car overcomes the gravity to do the same work, the larger the distance, the less force required, because the car power is certain, the output force is also limited, in order to avoid overload, so it is necessary to slow down the slope and increase the distance.

It is based on this principle that the winding mountain road can reduce the slope of the originally steep mountain by circling the mountain through the line, which also increases the mechanical efficiency.

It is easier to climb the mountain by car. In the era when bridge and tunnel technology was not developed, winding mountains and paving roads was a helpless choice to cross mountains and mountains. With the rapid development of human economy and technology, more and more highways cross valleys and ridges by erecting bridges and digging tunnels.

Because such a design is safer and can improve the stability of the vehicle, the driver does not dare to drive fast on such a road, so he can only drive slowly. Of course I do.

You know, because walking on mountain roads is particularly dangerous, if you design a winding road, you can slow down the moving car and effectively reduce the occurrence of accidents.

Because the mountain road is built around the mountain, it is always winding and winding, and if you go directly along the mountain, the road will be steep and prone to accidents.

It is to reduce the slope, and then get on the car to drive more stable, and this can also make the car drive faster. I know.

The main thing is safety considerations, if the mountain road is straight, then the inclination angle will be very large, the slope is also very large, once the vehicle is not powered enough to climb up, it is easy to lead to safety accidents.

First of all, the winding mountain road is a relatively common type of mountain road, and its main feature is that it winds around the slope of the highway and builds with the help of the hillside, with steep slopes and sharp bends, undulating and uneven. The winding mountain highway reduces the slope of the road according to the method of circling around the mountain according to the route, so that the car can go uphill, in the era when the bridge and tunnel technology is not advanced, the winding mountain road is the last resort to choose to trek through the mountains and wade through the water.

Whether it is a high-grade highway or other low-level highway, it is inevitable that the road around the mountainous area will have more or less winding sections.

The winding mountain highway is the principle of the inclined plane, under normal conditions, if the car wants to climb a relatively high mountain slope, if it goes up immediately, the inclination plus the force of the car itself, the friction resistance is more large, and the output power of the automobile engine is relatively limited, so the straight up is more laborious, but if the road surface is made into the slope of the spiral type or the "S" mode, the longer the slope, the smaller the friction resistance, the more energy-saving, so many winding mountain roads have chosen the design scheme of spiral type or "S" mode.

The winding mountain road is a relatively common type of mountain road, and its main feature is that it winds around the slope of the highway and is built with the help of the hillside, with steep slopes and sharp bends, undulating and uneven. When the car drives the same height of the 2 roads, if the car gets rid of the same situation of gravity to do the work, the road is larger, the force required is smaller, because the car output power is certain, the force output is also relatively limited, in order to prevent the load, therefore need to alleviate the inclination, improve the road. It is precisely according to this basic principle that the winding mountain road circulates around the mountain according to the route, and the slope of the slope road with a large slope can be reduced, so that the mechanical energy is expanded, and the car climbs the mountain more effortlessly.

With the rapid development of economic development and high technology, the highways that must trek through mountains and rivers have long been built with the help of terrain, and more and more are based on the construction of highway bridges and tunnels to cross the Rebirth Mountains and surpass the Grand Canyon.

The scientific truth is that the height is certain, if we have a longer inclined plane, the more labor-saving it will be, such a design can delay the pressure of the car, ensure driving safety, reduce the slope problem, make it more convenient for everyone to drive, and so on.

The scientific principle of this design is that through the principle of inclined plane, the S-shaped curve can increase the distance and reduce the force, so as to achieve the purpose of saving effort but not effort. It can also make driving more convenient.

First of all, this is the use of a simple mechanical slope principle that we have learned, which is to make the car more labor-saving when going uphill, and can also ensure the safety of people's lives, and the slope will be very small, so that the mechanical efficiency can become greater. So all in all, it's about saving effort.

Winding roads are a common type of mountain roads, and their main feature is that they ring around the mountains and rely on the construction of mountain slopes, with steep slopes and undulating slopes. When a vehicle is driving on two road sections at the same height, if the car overcomes gravity and does the same thing, then the greater the distance, the less force is required. Since the power of the car is constant, the output force is also limited, and in order to avoid overloading, the slope must be slowed down and the distance increased.

It is based on this principle that the winding mountain road can reduce the slope of the original slope with a large slope, improve the mechanical efficiency, and make it easier for the car to climb the mountain.

The design of the winding road is very effective, it is to build the road into a spiral or "S" shaped slope, the longer the slope, the less resistance, the greater the distance, the more effort will be saved.

Of course, it works, and the ring road goes up slowly by wrapping around the mountain, so that the slope of the uphill will be smaller.

The longitudinal slope of the winding mountain highway is large, and there are many sharp bends, which is not conducive to driving safety, etc., the winding mountain highway needs to pay attention to the special analysis of the long downhill slope, and try to avoid the long longitudinal slope and the small radius curve. The winding mountain road is a product of a compromise between the cost of the project and the traffic demand.

Because the mountain is high and the slope is large. In order to reduce the drag of the car. Build the road around the mountain, turn in circles. The slope of the road has been reduced. Reduced the ancestral power of the car. Speeds up the car.

In this way, the slope is smaller, and the road is built according to the shape of the mountain, which is safer to wind, and the car can drive safely.

Because the roads are built according to the shape of the mountain, it is safer to winding around.

This reduces drag and makes it easier for the car to go uphill, which is a reflection of the ingenuity of the designer.

Maybe it's because the bending can reduce the resistance, so it's easier to run.

It's all about physics, because the longer the distance, the less force is used to drive and the less tiring it is.

Because it may be that the design is like this, it will be safer to go around.

It may be that the length has been made longer, the slope has been slower, and the safety has been improved.

Because of the resistance, the car can go fast.

The winding road in the mountainous area uses the principle of inclined planes.

The winding road uses the principle of a simple mechanical slope that we have learned, and the purpose is to take advantage of one of the advantages of this kind of machinery, so that the car can save effort when going uphill. The slope from the top of the mountain to the foot of the mountain is called the slope, also called the slope or slope. Defining the specific shape of the inclined plane on the map is of some value for orienteering.

I believe that all partners should have experienced that when walking on the winding road, the shape is mostly zigzag or S-shaped. For early highway construction in China, the Panshan Highway would be the best choice at that time to build a road with simple construction technology, low maintenance cost and suitable for local transportation needs according to the terrain of China's mountainous terrain.

Building a mountain road directly in a mountainous area will cost much less than building a tunnel. In the middle and late stages of development, the curved mountain road is also a beautiful scenery, and many areas are also famous for the curved mountain road.

For car owners, the smoother the road, the faster they will drive, and the faster they will drive, and at the same time, they will save unnecessary trouble. For most car owners, this construction helps to smooth the road and reduce the resistance of the car when going up the hill. After all, less fuel consumption is what every car owner needs, and unnecessary savings are still needed to see the fuel cost of maintaining a car a year.

This is to reduce the inclination of the road surface. If you go straight up, the slope of the road will be close to 90 degrees, and it will be difficult for cars to drive up. A road that takes a little distance and reduces the slope to cause a curve can get the car up.

The purpose of this construction is to save labor, in the mechanical principle, it is like a wooden board to drag the car out, can be used by inertial force, very fuel-efficient.

Due to the amount of investment and traffic volume, the installation of bridge and tunnel structures is generally minimized in highway design. When the route needs to climb over the ridge, the route generally adopts an S-shaped extension line along the hillside to overcome the height difference and reduce the longitudinal slope of the route during climbing.

This saves a lot of effort and is relatively safe for the driver to drive.

The main purpose of this construction is to reduce the slope of the mountain, so that it can be easily driven up the mountain.
