Background technique

Landslides are one of the most common geological disasters in my country, among which there is a special type of landslides. In the contiguous rock slope with interbedded sand and mudstone, when there are cracks developed on the trailing edge of the slope, under poor rainfall conditions, the rainwater seeps into the interior of the slope through the cracks, forming a water column on the trailing edge, which affects the structure of the slope. outward thrust. At the same time, the rainwater will seep down along the weak sand-mudstone interlayer inside the slope, and the mudstone is prone to softening when it encounters water. After the mudstone is softened, its shear strength will decrease sharply. When the anti-slip force provided by the surface is less than the sliding force, the rock and soil mass will undergo plane slip shear failure along the weak surface.
