The Revival Mechanism and Stability Analysis to Jiaju Landslide of Danba County in Sichuan Province

Jiaju landslide is a huge ancient accumulation landslide,which has been paid so much attention to for being located in the Jiaju Tibetan villages scenery tourism area. This article analyses the typical accumulation landslide considering the geological environment, by configuration, structure, and development characteristic of its deformation and destruction, shows that it is a discontinuous comprehensive deformation mass which is formed by multistage and multi-layer sliding, and the history of formation and evolution is complicated. Its deformation and revival are closely related to earth-structure,river erosion and human engineering activity,and it has a character of long-term interval creep-sliding deformation, mainly partial slipping and sliding, that can hardly cause whole deformation and destruction. This research provides a basis to process next period of landslide monitoring and controlling.
