Study on Time-Space Motivation and Operation Mechanic of Landslide - A Case of Zhenzilin Landslide in Sichuan-Tibet Highway

Abstract:

The time-space movement feature of landslide was a geological process that landslide mass change from a state to another under the effect of internal and external factors. The ground surface and deep displacement feature of landslide with time and space was a reflection and externalization also a trace record of landslide time-space movement. Particularly, deep displacement of landslide provided direct and reliable evidence for studying space-time motion characteristics of slide. This paper studied on ZhenziLin landslide in Sichuan-Tibet highway, based on monitored deep displacement information of boreholes in landslide. It systematically analyzed time-space movement features and operation mechanic of integral revived area, disturbed deformation zone and foreland slump zone of landslide from the aspects of accumulated or relative displacement and displacement vector etc. of confirming or potential slide plane and hole top at different time. Results obtained provided data and dependence for studying landslide stability prediction.
