What are the prevention and control measures for landslides?

1. Establish a geological disaster monitoring and early warning system project.

2. Establish a monitoring team that combines professional personnel with group measurement and group prevention, and establish a monitoring network based on professional teams for important geological disaster points.

3. Establish monitoring outlets for other geological disaster points, which are mainly based on group measurement and group prevention, and combined with the guidance of professional teams and regular inspections, through professional monitoring systems, group measurement and group prevention monitoring systems, and information systems.

4. Establish an expert analysis system for geological disasters in mountainous areas.

5. Determine the department for issuing early warning information and standardize the form of early warning information.

6. Establish a linkage mechanism. The disaster prevention and relief work of landslides involves monitoring, early warning, disposal, disaster relief and other aspects, and requires all units and departments to perform their duties and cooperate closely.

1. Landslide: refers to the effect and phenomenon that a certain part of the rock and soil on the mountain slope moves to the bottom of the slope as a whole due to shear displacement along a certain weak structural plane (zone) under the action of gravity (including the gravity of the rock and soil itself and the dynamic and static pressure of groundwater).

2. It is commonly known as "walking the mountain", "collapsing the mountain", "slippery ground", "slippery", etc. It is one of the common geological hazards.

3. If the landslide is mixed with rainwater or river water, it will evolve into a debris flow.

4. In terms of the influence of internal and external stresses and human actions, the areas of crustal movement and the areas with frequent human engineering activities are landslide-prone areas.

5. External factors and effects can change the basic conditions for landslides, thereby inducing landslides.

1. Prevent water from entering the landslide area and repair the interception ditch; Construction of drainage ditches in the landslide area. Cover with slurry stone or artificial vegetation to prevent infiltration.

2. Shotcrete retaining surface or hanging reinforcement mesh shotcrete.

3. The methods of water removal are: horizontal drilling and dredging; vertical hole drainage; Shaft pumping; tunnel dredging; Support blind groove.

4. Improve the mechanical strength of the slope rock and soil, improve its anti-sliding force, and reduce the sliding force. Commonly used measures are: slope cutting and load reduction; Improve the stability of the slope by lowering the slope height or slowing the slope angle.

5. Slope artificial reinforcement. Commonly used methods are: building retaining walls, retaining walls, etc.; reinforced concrete anti-slide piles or reinforced piles; prestressed anchors or cables; Consolidation grouting or electrochemical reinforcement; SNS slope flexible protection technology, etc.; Inlay and patch grooves.

6. For the cracks, cracks and cavities in the slope, the cavities can be filled with flakes, cement mortar ditches, etc.

1. To prevent landslides, we must first do a good job in the assessment of geological disaster risk, and pay attention to the stability of the slope when selecting the site and homestead.

2. To prevent landslides, it is necessary to do a good job in reinforcing the mountain. The measures mainly include eliminating or mitigating the hazards of water, changing the shape of the landslide body, setting up anti-slide piles, and improving the soil and rock properties of the sliding zone. For example, the construction of interception ditches and drainage ditches to intercept the surface water on the slope and lead the water out of the landslide body along the drainage ditch, the effect of groundwater that induces landslides can be eliminated.

3. It is also necessary to regularly check the changes in the surface of the house and the hillside. This includes checking whether there are cracks or cracks in the walls of the house, whether the telephone poles or trees on the slope are inclined to one side, and whether the road surface near the house has been deformed.

2020 is an accident-prone year, the epidemic in the first half of the year has just been controlled, and the regions have just improved, and the floods in the second half of the year will follow, causing natural disasters such as landslides. Everyone joked that the rat is the eldest brother in the zodiac, and the eldest brother took all the bad luck in the next place at the beginning, so there is an accident-prone year in 2020.

The cause of the landslide event is not only heavy rain, the mountain is generally composed of all kinds of rock, soil, some loose structure of the slope weathering ability is relatively poor, under the action of rain, it is easy to collapse part of the collapse phenomenon to cause landslide. However, when some people have a relatively large slope due to wind and sun, the structure is discontinuous, and the fault phenomenon is easy to occur, and the landslide phenomenon is also easy to occur when the force exceeds the support point.

In fact, some landslides can be avoided, follow the laws of nature, do not overexploit the land resources on the mountain. Protect the weathering of several trees on the mountain. A lot of unnecessary injuries can be avoided.

Natural disasters require people to take countermeasures to ensure their own safety.

The main inducing factors of landslides are:**, rainfall and snowmelt, surface water scouring, soaking, continuous erosion of the foot of the slope by surface water bodies such as riversUnreasonable human engineering activitiesLandslides can be induced by excavation at the foot of the slope, loading on the upper part of the slope, blasting, reservoir storage (discharge), mining, etc., as well as tsunami, storm surge, freeze-thaw and other effects can also induce landslides.

The activity intensity of landslide is mainly related to the scale, sliding velocity, sliding distance and potential energy and function of landslide. Generally speaking, the higher the position, the larger the volume, the faster the moving speed and the farther the moving distance, the higher the activity intensity of the landslide and the greater the degree of harm.

There are many factors that cause landslides, first of all, natural causes, if it rains frequently, the surface slope is often washed out and will cause landslides; Secondly, there are man-made reasons, pruning the railway, excavating the foot of the mountain will cause landslides, because this will cause the lower part of the mountain to have no support.

The factors that cause landslides are, **, which can change the geological structure and surface slope of the mountain. This causes the soft structural surface to slide down, resulting in landslides. In addition, the factors that cause landslides are large-scale heavy rainfall, which washes away the soil in the mountain, and accumulates together to form landslides; In addition, excessive human engineering activities can also lead to landslides.

The first reason is that the soil is relatively soft and easy to be washed down, the second reason is that the moisture in the soil is too large recently, if it rains for a long time, it will cause this result, and the third reason is the slope problem, if the slope is too steep, it is easy to cause landslides.

The main factors that cause landslides are geological activities, meteorological disasters, and human factors. Such as **, flash floods, man-made excavation, etc.

Random felling of trees, soil erosion and excessive rainfall, or random excavation of mountains resulting in loose soil, or the recent rainstorms have continued to rain.

Landslide is a heavy rain or rain that overwhelms the mountain, is disconnected from the weak area of the mountain, and slides as a whole, causing a landslide.

1. Establish a geological disaster monitoring and early warning system project. Establish a monitoring team that combines professional personnel with group surveying and group prevention, establish a monitoring network based on professional teams for important geological disaster points, and establish group measurement and group prevention for other geological hail and shank disaster points.

And with the professional team guidance and regular inspection combined with the monitoring network, through the professional monitoring system, group measurement and prevention monitoring system, information system to achieve timely monitoring of geological disasters in mountainous areas, for the prevention and control of geological disasters and relevant departments to protect the safety of people's lives and property, disaster prevention and mitigation decision-making and implementation to provide scientific basis and technical support.

2) Establish an expert analysis system for geological hazards in mountainous areas. After the danger of a landslide body, the local geological disaster prevention and control work headquarters convenes a meeting of geological disasters and related experts to analyze the information collected by the monitoring and early warning system, judge the state and early warning level of the landslide body, estimate the impact range of the surge, and form consultation opinions for local decision-making reference.

3) Determine the department for issuing early warning information and standardize the form of issuing early warning information. The Emergency Response Law of the People's Republic of China stipulates that when a natural disaster, accident disaster or public health event that can be warned is about to occur or the likelihood of occurrence increases, the local people at or above the county level shall, in accordance with the relevant laws, administrative regulations and the authority and procedures stipulated by the People's Republic of China, issue the corresponding level of warning, decide and announce that the relevant area has entered the early warning period, and at the same time report to the people at the next higher level, and if necessary, they can report to the next higher level. and inform the local garrison and the people of the adjacent source or the relevant area where the surplus can be endangered.

Therefore, the early warning information should be clearly issued by the local government in a formal form, and all departments should take corresponding measures according to the level of early warning issued by the local government.

4) Establish a linkage mechanism. Landslide disaster prevention and relief work, involving monitoring, early warning, disposal, disaster relief and other aspects, the need for all units, departments to perform their duties, close cooperation, only under the unified leadership of the local government, the relevant units as a whole, take the initiative, active response, in order to avoid or reduce the loss caused by landslides to the greatest extent.

1. Establish a geological disaster monitoring and early warning system project. Establish a monitoring team that combines professional personnel with group measurement and group prevention, establish monitoring outlets based on professional teams for important geological disaster points, and establish monitoring outlets based on group survey and group prevention for other geological disaster points, and combine them with the guidance of professional teams and regular inspections.

2) Establish an expert analysis system for geological hazards in mountainous areas. After a landslide is in danger, the local geological disaster prevention and control headquarters convenes a meeting of geohazard and related experts to analyze the information collected by the monitoring and early warning system and judge the status and early warning level of the landslide.

3. Establish a linkage mechanism. Landslide disaster prevention and relief work, involving monitoring, early warning, disposal, disaster relief and other aspects, the need for all units of the town, each department to perform their duties, close cooperation, only under the unified leadership of the local **, the relevant units as a whole, take the initiative, active response, in order to avoid or reduce the loss caused by the landslide to the greatest extent.

Protective measures for landslides include but are not limited to: 1. Geological disaster monitoring and early warning system. 2. Geological disaster detection outlets.

3. Change the shape of the landslide mountain. Fourth, set up anti-slide piles at the mountain. 5. Set up mountain protection nets.

6. Fill the cracks in the slope. 7. Reinforcement of the overall or edge strength of the slope.

Landslide is a kind of geological disaster, which refers to the phenomenon that a part of the soil and rock on the mountain slope moves towards the bottom of the slope under the action of the earth's gravity, causing damage to the settlements, roads, and farmland below the slope.

The causes of landslides are mainly man-made and natural phenomena, man-made are mainly caused by some unreasonable engineering activities, and natural phenomena are usually related to water, such as long-term rainfall leading to the loosening of mountain soil clods and landslides.

There are generally some abnormal phenomena before the occurrence of landslides, which can be used as a warning reference, such as skewed trees on the hillside, skewed power poles, leakage of the slope pond, and pollution at the foot of the slope.
