Most landslide disasters occur in connection with changes in groundwater level. The rise of the underground water level causes the volume weight of a landslide body to be increased, the effective stress of a sliding surface is reduced, the shear strength is reduced, and further the landslide is unstable. For the side slope, when the water level in front of the slope is rapidly reduced, groundwater in the slope seeps outwards to generate seepage force, the downward sliding force is increased, and the landslide is promoted to be unstable. Therefore, the underground water in the side slope is discharged in time, the stability of the underground water level is kept, and the method is very key to the prevention and treatment of landslide disasters and emergency treatment.
