Sloping soil. Can be divided into two categories, one is naturally formed, called natural soil slope, or natural soil slope, and the other is formed by excavation or filling, called artificial soil slope.
Stability analysis of soil slope is one of the important topics in soil mechanics. To evaluate the stability of soil slope, the concept of sliding wedge is applied in soil mechanics, that is, to see whether the shear stress on the potential sliding surface in soil slope exceeds the shear strength of soil. Once exceeded, part of the soil in the soil slope will slide along the sliding surface. The shape of the sliding surface in the soil slope depends on the cross-sectional structure of the soil slope and the properties of the soil, and it can be assumed as an arc surface, a broken section composed of several planes or a curved surface with any shape.
Soil slope refers to sloping soil. Generally, it can be divided into natural soil slopes (soil slopes naturally formed due to geological processes, such as mountain slopes and river bank slopes). ) and artificial soil slopes (artificial earth slopes, such as foundation pits, canals, earth dams, embankments, etc. ). When the top and bottom surfaces of a soil slope are horizontal and extend to infinity, and are composed of homogeneous soil, it is called a simple soil slope.
Under the influence of natural or human factors, a part of rock mass or soil on a soil slope moves down along an obvious interface, which is called sliding or slope failure.
