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 landslides in mainland China in the 20th century. A number of geo-mechanical models have been identified: the three sections model (sliding; tension cracking; shearing), retaining wall collapse, horizontal-pushing in horizontal strata; large-scale toppling in counter-inclined strata; the creep-bending-shearing model etc. Large-scale rock landslides are generally accompanied by sudden brittle failure of the locking section along the potential sliding surface. The paper discusses the importance of this locking section which is key to assessing slope geohazard and to the development of control/mitigation measures.
