What is a Lateral spread?

The side slip is almost horizontal sliding, and the bottom of the sliding surface is usually a weak rock layer, which affects the overlying hard rock layer due to the plastic flow of the soft rock layer. Depending on the sliding material, it can be divided into rock mass side slip, rock cutting side slip, and soil side slip. It is characterized by the disordered huge rock mass dumping in various directions, the particle size decreases with the increase of the distance, and the terrain becomes more chaotic; the rock mass is separated by a huge crack and a linear subsidence, and the collapse can be Occurs on a very gentle slope (< 10°).
