Basic types and active features of loess landslide

Abstract

On the basis of how the sliding body is composed of and where sliding plane exists, landslides in loess area can be divided into four basic types.They are homogeneous loess landslide, loess interface landslide, loess-mudstone layer plane landslide and loess-mudstone cutting layer landslide. The characteristics of loess interface landslide and loess-mudstone layer plane landslide are low sliding velocity, short sliding distance and low stability after sliding. And the characteristics of homogeneous loess landslide and loess-mudstone cutting layer landslide are high sliding velocity, long sliding distance and high stability after sliding except its scarp. Basic laws mentioned above have some guiding significance and practical value.
