Study on time-space motivation and operation mechanic of landslide--A case of Zhenzilin landslide in Sichuan-Tibet highway

摘要

The feature of landslide time-space movement was a geological process of landslide geological mass from a state to a other state under internal and external factors action. The feature of displacement of landslide ground surface and deep with time-space was a reflection and externalization and a trace record of landslide time-space movement. Particularly, deep displacement monitoring of landslide provided direct and reliable evidence for study space-time motion process of slide volumes. A case study of ZhenziLin landslide in Sichuan-Tibet highway, based on deep displacement monitoring information of bore holes in landslide, systematic analysis time-space movement features and operation mechanic of integral revived area, disturb and deformation zone and foreland slump zone of landslide from accumulated or relative displacement and displacement vector etc. of confirming or potential slide plane and hole top position at several times. Results obtained will provide data and dependence for study landslide stability prediction.
