Cause Analysis and Treatment for Landslide of Tianshan Expressway

Based on the slope engineering geological conditions and landslides deformation signs,cause analysis on the landslide has been made.It has been put forward that the slope structure,and a large area of surface water,bedrock confined water and slope excavation are the main reasons leading to landslide.According to the different levels of deformation,the landslide is divided into three zones,with distinguishing between primary and secondary treatment works and adopting remedial measures for these three areas.Through the integrated use of anti-slide piles,steel flower tube grouting,anchor and drainage works in the framework of measures to clean up the landslide,good rectification results have been reached.This article analyzes the causes and treatment of landslide,and provides landslide prevention and treatment of diseases for referencing for other same works.
