Relying on the small landslide in the southwest mountainous area as the object,using numerical simulation methods,the impact of multi-physical parameters on the landslide thrust is explored by the introduction of orthogonal tests and the use of range analysis method.The results show that:the distribution curve of landslide thrust after the wall of anti-slip retaining wall is"bulging belly",and the landslide thrust tends to be 0 within a certain range near the slope surface.The folding coefficient of the cohesion of the slip belt and the angle of internal friction and the depth of the anti-slip retaining wall have a greater influence on the size of landslide thrust.The depth of the anti-slip retaining wall has a greater influence on the height of the action point.The point of action of the landslide thrust is between 20％-29％of the upward vertical height of the bottom of the retaining wall,which is a deviation from the assumption in the rigid-body limit equilibrium method.
