Analysis of Treatment Effect of "Pin" Type of Anti-slide Piles for Suoertou Landslide
摘要
Abstract
"Pin" type anti-slide pile prevention programs is used to treat Suoertou landslide,for the evaluation of the effect of its governance,by means of the numerical simulation software FLAC3D to compare the stress,displacement of landslide and trends when taking the "Pin" type of anti slide piles and no piles.As a result that after the anti slide pile supporting measures,the landslide displacement decreases,and the slopeis stable.The governance effect is marked.The slope stress is concentrated on 10 m platform and local collapse may occur under the unfavorable load,in order to increase the safety margin,we suggested a retaining wall.The retaining side pile has uniform stress.The front row pile displacement is significantly less than the back row pile in "Pin" type of anti slide,so in order to make the anti stress more reasonable,it is appropriate to increase the row pile spacing or reduce the front pile cross section during the design.关键词
