Monitoring and analysis of reinforcement effect of anti-slide piles of a slop

Ye-shuigou landslide as a hazard of the gas transmission pipeline project for Zhongxian-Wuhan, anti-slide piles have been taken to ensure the safe operation of pipeline. In order to guarantee construction safety and obtain the internal force distribution data as well as objective to evaluate the working state of the resistance slide, the long-term GPS for surface displacement and slide-resisting stress monitoring have been carried on. Establishing the model of single steel rectangle cross section with flexural members gave the definition of safety reliability to quantitatively determine the slide-resisting working state. The surface displacement of the landslide and stress monitoring result analysis shows that the slide resistance works and is in safe situation, consequently, regulation engineering has achieved obvious effect, and restrained the further deformation of the landslide.
