How to prevent landslides

1, to prevent landslides, the risk assessment of geological disasters should be done first, and the stability of slopes should be paid attention to when selecting sites and homesteads.

2. To prevent landslides, we must do a good job of mountain reinforcement. These measures mainly include eliminating or reducing the harm of water, changing the shape of landslide, setting anti-slide piles and improving the geotechnical properties of sliding zone. If intercepting ditch and drainage ditch are built to intercept the surface water on the slope and lead the water out of the landslide along the drainage ditch, the effect of groundwater-induced landslide can be eliminated.

3. It is also necessary to regularly check the changes of houses and slopes. Including checking whether there are cracks in the wall of the house, whether the poles or trees on the slope are tilted to one side, and whether the road surface near the house has been deformed.

Causes of landslide:

(1) Geotechnical engineering type. Rock and soil are the material basis of landslide.

(2) Geological structural conditions. Only when the rock and soil forming the slope are cut and separated into discontinuous States by various structural planes can it slide down.

(3) Topographic and geomorphological conditions. Landslides can only occur under certain landforms and slopes.

(4) Hydrogeological conditions. Groundwater activity plays an important role in the formation of landslides.

(5) As far as the influence of internal and external stress and human action is concerned, the areas with frequent crustal movement and human engineering activities are landslide-prone areas. External factors and actions can change the basic conditions of landslides, thus inducing landslides.
