摘要
Abstract
Dahuichang landslide site is located in the Xishan area of Beijing.The characteristics of the Dahuichang Road landslide were determined through on-site investigation,trenching,drilling,and geotechnical testing.The landslide range includes one main landslide and one associated landslide.The main landslide has an inverted V-shaped plane shape,and the associated sliding slope has a circular chair shaped plane shape.Its scale is small with a total area of 2,322 square meters and a total volume of approximately 4,644 cubic meters.The sliding surface is a plane formed along the underlying shale layer of the sliding body.Overall,the Dahu-ichang Road landslide is a small traction type shallow rock landslide that slides along the bedrock surface of the slope.The stability analysis of the landslide under three working conditions shows that the landslide is in a stable state under natural and seismic con-ditions.Landslides under continuous rainfall conditions may experience instability and damage.The treatment project adopted a comprehensive treatment plan of"cleaning the landslide accumulation body+Intercepting and drainage ditch+anchor rod lat-tice beam+gravity retaining wall".关键词
