As shown in Figure 3, the bedding slope is considered as a plane problem, and the sliding surface is assumed to be a circular arc surface. The sliding rock mass is regarded as a rigid body. The stability of the slope is related to the sliding force and anti-sliding on the sliding surface. Resistance is related. When the bedding slope is in a stable state, the sliding force is less than the anti-sliding resistance. When the bedding slope is affected by various internal and external factors (such as slope lithology, earthquake, rainfall, etc.), the sliding force will increase. The anti-sliding resistance will decrease, and the sliding force will be greater than the anti-sliding resistance. At this time, the slope will be unstable and the sliding rock mass will slide along the sliding surface to form a bedding curved landslide.
