摘要：

Based on a macroscopic analysis of geological characteristics of landslides and indoor experiments, the lithology, grain ingredients, mineral components, microstructure, physico-mechanical behaviors and deformation under the reservoir backwater condition of soil in sliding zone in No.1\ riverside landslide soil of Huangtupo landslide are analyzed. The results show that the indispensable conditions for the soil in sliding zone to be easily water-saturated and softened include a high content of clay or powder, rather obvious polished surfaces and scratches under the influence of deep creeps and hydrophilic clay minerals and soil with a sheet structure; the creep deformation of slumped mass is a vital consequence of mechanical strength decrease of soil in sliding zone being water-saturated.
