A Case Study on the Treatment Project for the Shallow Landslide with Strip Loose Covering

摘要

Landslide with strip loose covering, the method to deal with the landslide mainly included "slide-resistant pile,Gravity retaining wall, removed the material at the rear of the slide, backfill the material at the toe of the slide, vegetation protection and drainage engineering" etc [1].In the design of project management need to calculate stability and thrust[2], this paper according to the example of "Ping Zi mountain landslide treatment engineering construction design in Ningnan County, Sichuan Province", to study the measure to retaining the landslide that is classified into layered loose cover aliding.The surface of landslide, with shallow strip shape is an elongated, the characteristics including berm shaped, anterior elevation etc, retaining engineering not only satify the barrier down the sliding body requirements, but also to prevent the slope cutting out from the top of the landslide.According to the real terrain, it is necessary to adopt grading supporting measures and comprehensive control of drainage system.
