Study on the Development Characteristics of Landslides and Remediation Measures of Alpine Valley Accumulation
With the background of Jinsha River Basin Alpine Canyon Geomorphology Area,we select the K8+330～+720 section of Manluo Road of G215 line as the research object,the morphology and scale of landslides,damage characteristics and disaster mechanism are researched under the comprehensive on-site investigation and geologic boreholes and other basic data.The regional stability and evaluation are carried out by selecting the geological profile of the main slip surface.The results shows that the status quo of the upper slope on the left side of the route and the lower slope on the right side of the route are in the state of unstable and basically stable,and in the state of unstable and unstable under the influence of external factors such as rainfall,etc.The treatment measures are divided into regions and fall in stages.The upper slope of K8+400～+500 section adopts anchor frame beam+short wall to fix the slope,and the lower slope of K8+390～+720 section adopts anti-slide piles to support.
