Why can t the high speed rail line be built in a straight line, instead of curved forward?

Why can't the high-speed rail line be built in a straight line from beginning to end, but can only bend forward?

Because the construction of the high-speed rail railway needs to consider the geological conditions and construction costs, there will be a bending.

First of all, because high-speed rail is not point-to-point, there will be many stations on a line, and of course these stations will not all be in the same straight line.

And not all roads are straightforward. When building roads, it is easy to encounter obstacles such as mountains and rivers that cannot be passed normally. Then if there is no bypass in the construction, the tunnel is forcibly dug and the bridge is built, which will lead to a very high capital requirement for the construction of the entire high-speed railway.

Because there is no way to achieve no loss on the planned route, there are some buildings, farmland and lakes that cannot be avoided and demolished, and bending forward can avoid unnecessary losses.

Why can't the high-speed rail line be built in a straight line, instead of curved forward?

Today, with the rapid development of science and technology, people can choose more and more diversified means of transportation when traveling, mainly including high-speed rail, bullet trains, etc. Because their appearance has brought great convenience to most people, then, when you take the high-speed rail, you will find that there are often turns, many people are puzzled by this, when building the high-speed rail railway, why not build a straight line, have to be built into a curved one?

Convenience. The original intention of building high-speed rail is to provide convenient travel conditions for people and promote the development of various cities. Because the location of many cities is not in a straight line, if it is built in a straight line, it will inevitably cause omissions. As a result, people in many cities need to take a long detour to another city to take the high-speed rail.

In this way, it will bring great trouble to the vast majority of the people, and everyone will definitely think that it is more convenient to take an ordinary train. For example, the world's longest Beijing-Guangzhou high-speed railway, it passes through Shijiazhuang, Zhengzhou, Changsha and other important cities, these cities are not in the same straight line, natural high-speed rail can not be built in a straight line.

Natural conditions also have a great impact on the construction of high-speed rail.

We will find that these bullet trains are built along the valley. That's because the climbing ability of the EMU is not strong, because in the process of running the EMU, it only relies on the friction of the track to advance, and the force on its friction surface is also very small, if the train wants to climb, then its high climbing angle must not exceed 25 degrees. Some people may say that there is no problem in opening a mountain, but opening a mountain and building a road is also a very difficult project, and the cost is also very high.

At the same time, the ecological environment along the train line will also be damaged to a certain extent, and it is basically impossible to build the train line in a straight line.

Natural conditions also have a great impact on the construction of high-speed railways, as we all know, our country has a vast territory and complex mountains and rivers. For example, the Beijing-Shanghai high-speed railway not only crosses the flat North China Plain, but also passes through the Jiangnan region, which is covered with a dense river network. Generally speaking, the cost of building a bridge is much lower than that of drilling, if it is built according to the straight-line distance between Beijing and Shanghai, this high-speed railway is only more than 1,000 kilometers, but in order to avoid the mountainous area, the high-speed rail can only bypass Jinan and Xuzhou, the distance has reached more than 1,300 kilometers.

The tracks are laid according to the characteristics of the train.

Straight-line distances are often the fastest, and curves can increase the safety hazards of the train. Therefore, in fact, our country's railway lines have always been built with the concept of straight running, but in the process of construction, due to the limitations of terrain and urban geographical location, there is no better way to make the high-speed rail run normally except for adding curves; However, in general, in this case, the curve will be expanded, so that the centrifugal force will be reduced, and the risk will not be increased due to the high speed of the high-speed rail.

If you drive in a straight line, you will inevitably pass through various densely populated cities, and you may even have to pass through the city centers and scenic spots of some cities. It will cause great inconvenience to people, and at the same time, it will also add invisible pressure to these cities. Such an approach is obviously unwise, so it is better to add an extra curve than to go against the original intention of building a high-speed railway.

Due to geological reasons, some cannot be built in a straight line; When crossing a mountain, it is time-consuming and laborious, which greatly increases the cost, and some geological loose sections, and even ravines, need to be bypassed.

It is because if it is built in a straight line, it may affect people's travel, and it will also pass through the scenic spots of the city, and it will also pass through many places with a large amount of **, which will bring inconvenience to people.

Because it is necessary to avoid smashing tunnels through mountains, it is also to avoid some sections where the geology is relatively fragile or settled, which can improve the safety of driving.

Straight is of course the best, short distance investment savings. However, due to the influence of topography and features, some places must be built into curves. For example, there is a big mountain in front, and the geological conditions are very poor, and the tunnel is directly passed, the investment is high and the safety hazards are large, and it is difficult to maintain it in the later stage, so it can only be curved around.

There are also stations that need to enter or be close to the city, which needs to be in line with urban planning. You can't fix it as much as you want...

If the length of the straight line is too long, it will lead to the monotony of the highway alignment and the lack of change in the environment. China's "Highway Route Design Code" stipulates: guide the driver's line of sight, maintain the continuity of the line, avoid the use of long straight lines, and pay attention to the coordination with the local environment and landscape.

There are too many mountains and rivers in China, and there are residents living in some places, and there are many complex geographical factors, not that the distance in a straight line is the shortest, so there may be no developed circuits in China.

Because in the places where the high-speed rail passes, not everything can be dismantled, and some things are not allowed to be dismantled.

The first is the safety factorThe straight-line speed is faster, uncontrollable. Secondary isGeolocation causedIt cannot be built in a straight line.

At present, China's high-speed rail technology has reached the highest level in the world, and the high-speed rail technology has lasted for several years from beginning to end, and now the high-speed rail has shuttled through major cities in China. Not only that, the high-speed rail produced in China has gone abroad and gone to the world. Today's high-speed rail has become the calling card of our country.

The development of high-speed railway technology has made our lives develop slowly and rapidly, the development of high-speed railway technology has provided convenience for travel, China's high-speed railway technology has been applied to our country, and now high-speed railway has entered our lives. People's understanding of high-speed rail technology in everyday life may make some friends sit on the high-speed rail unnoticed, looking at the surface of the rails, and there are bends on the high-speed rail tracks.

High-speed tracks are usually straight tracks and are faster than curved tracks, but there are other considerations. This includes:Economic, security and practical factors。All of these conditions affect the track design.

First,Economic factors

It is necessary to ensure attendance, so high-speed rail is used to connect the already established metropolises and must connect the state capital along the route.

Second,Safety considerations

I learned in childhood that life is more important than everything. The same is true from the point of view of high-speed rail maintenance. Due to the undulating topography of China, where mountains and rivers are intersected, and the geology of each region is very different, the construction of railways should be based on geographical conditions and the topographical distribution of each region.

Third,Practical and technical elements

The purpose of rehabilitating high-speed rail is to convert passengers and freight, while passenger rail and freight rail are different. Passenger railways are tasked with connecting cities with cities, so make sure to design curved tracks.

A lot about the technical layer, so it is designed to bend under certain technical conditions.

Curved railroad tracks can reduce air resistance.

I think it's because there are a lot of places to avoid, so you can't always make straight lines.

I think it may be because the curved track is more suitable for the fast driving of high-speed rail.

Because it's still safe for the speed of the car.

Why should high-speed rail tracks be curved instead of straight? Praise the engineer after reading it.

What are the main influencing factors for the construction of high-speed rail lines, in fact, junior and senior high school geography have been learned, and the primary consideration is topography, rivers and mountains. But today, rivers have a much smaller impact than mountains, because it's easier to build bridges than to drill holes. Now almost all the high-speed rail lines are elevated, and it was originally meant to be bridged, and according to China's current infrastructure level, it is not a problem to build a bridge.

However, drilling is relatively difficult, there are more things to consider, and the cost is also high.

1. The high-speed rail in the city, because it requires a large number of demolitions, it is impossible to take a straight line to avoid houses and some other buildings, and it is not possible to take a straight line completely when entering the station.

2.The high-speed rail line between cities cannot be completely straight due to the topography, because the cost is too high, and some peaks and river valleys must be avoided.

3.If all high-speed rail is completely straight, then it will not be able to connect all cities to each other, and thus it will not be able to achieve the maximum economic benefits.

The high-speed rail line does not want to build a straight line, it can build a straight line. It is necessary to consider whether the geological terrain is suitable for construction, but also to consider the investment cost.

At the same time, it is necessary to consider the economic benefits of each region. The state has invested heavily in the construction of high-speed rail, not only for convenient and fast transportation, but also to drive the economic development of various regions.

Economic factorsThe construction of high-speed rail is mainly used to connect the large cities that have been formed, because passenger transportation is not profitable, so it is necessary to ensure the attendance rate as much as possible. The route of the high-speed railway, as well as the cities connected, need to take into account the degree of development of the city, and the economic and political status of the city, so it is necessary to try to connect the provincial capitals and important prefecture-level cities along the line.

A completely straightened line will inevitably pass through some cities with secondary economic status, which is not conducive to development from an economic point of view, and the macro drive to the country will be lower.

In fact, the national high-speed railway has always been built in a straight line, because only a straight line can run at the highest speed, and the straight line is also the safest and most ideal for EMUs. Even if there are curves, the radius of the curves will be particularly large. Because the speed of the EMU is very fast, the centrifugal force is also very large, and it is easy to have potential safety hazards due to many curves or small repair radius.

The reason why some high-speed railways have curves is because of the influence of terrain, environment, and the location of urban stations. There is no way, there must be curves in order to achieve the most ideal state of high-speed rail operation.

Therefore, the country is building high-speed railways in the most reliable, safest, most effective, and most beneficial way for everyone.

Why can't the high-speed rail line be built in a straight line, instead of curved forward?

China's railway network is so developed and dense, but why is there no straight railway? Anyone who has been to school knows that the straight line between two points is the shortest, but when building high-speed rail, this is not the case.

Nowadays, China's high-speed rail is developing rapidly, more than 20 countries are using China's high-speed rail technology, and everyone is enjoying the convenience that high-speed rail brings to us, I don't know if there is such a phenomenon, high-speed rail lines are crooked.
