Description

technical field [0001] The invention relates to the technical field of landslide prevention and control engineering, in particular to a calculation method and application of a horizontal pushing type landslide movement distance. Background technique [0002] Horizontal push landslides are a very special type of landslides that commonly exist in the red beds of the Sichuan Basin and the Three Gorges Reservoir area. Mostly developed in the slopes of near-horizontal rock formations, the dip angle of the rock formations is generally only 3-5°, and the steepest does not exceed 10°. The landslide is pushed out horizontally by the combined action of the hydrostatic thrust of the water filled in the cracks of the rock mass and the uplift pressure generated along the slip surface. Therefore, this type of landslide is called a horizontal push landslide. The inclination angle of water-filled fractures is generally close to vertical, and the inclination angle of the slip plane is consi...
