Mechanisms of large-scale landslides in China

摘要: Large-scale landslides in western China are famous for their size, complex formation mechanism and serious destruction. Data were collected from some typical large-scale mainland the 20th century. A number of geo-mechanical models have been identified: “three sections” model (sliding; tension cracking; shearing), “retaining wall collapse”, “horizontal-pushing” horizontal strata; toppling counter-inclined creep-bending–shearing etc. rock generally accompanied by sudden brittle failure “locking section” along potential sliding surface. The paper discusses importance this which is key to assessing slope geohazard development control/mitigation measures.
