In order 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. If the slope is an ancient landslide, the loose earth-rock layer on the slope is thick, the dip angle of the rock layer is the same as that of the slope, and it contains weak strata, it is not suitable to be selected as the construction site.
The second is to do a good job in strengthening mountains. 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.
In addition, we should 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.
