天（津）汕（尾）高速公路新铺滑坡原因分析及治理

天（津）汕（尾）高速公路新铺互通根据边坡工程地质条件、滑坡变形迹象，对滑坡原因进行分析，提出坡体结构、大面积地表水、基岩承压水和边坡开挖是导致滑动的主要原因。根据变形程度的不同将滑坡划分为三个区，治理工程分清主次，对这三个区采取针对性的治理措施，综合运用抗滑桩、钢花管注浆、锚杆框架与排水工程措施治理该滑坡，整治效果明显。

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.
