以金沙江流域高山峡谷地貌区为背景,选取G215线满洛路K8+330～+720段堆积体滑坡作为研究对象,综合现场调查及地质钻孔等基础资料,对滑坡的形态规模、破坏特征及灾变机理等进行研究,选取主滑面处的地质剖面,分区域开展稳定性分析及评价.结果表明:路线左侧上边坡、右侧下边坡的现状分别为欠稳定、基本稳定状态,在降雨等外部因素影响下分别为不稳定、欠稳定状态.采取分区域、分段落的处治措施,K8+400～+500段上边坡采用锚杆框架梁+矮墙方式固坡,K8+390～+720段下边坡采用抗滑桩支挡.
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.
