莘口滑坡稳定性评价及应用

Stability Evaluation and Application of Xinkou Landslide

文章结合工程地质调绘、钻探与室内试验成果,分析了莘口滑坡的形成机理,认为莘口滑坡为顺层——推移式滑坡。文章采用传递系数法对滑坡进行了计算分析,认为滑坡目前处于欠稳定状态,在暴雨或持续降雨作用下极易失稳滑动。在此基础上,提出了线路左移抬高纵坡以填方从滑坡前缘通过的线路优化方案建议。

Based on the results of engineering geological mapping, drilling and laboratory tests, this paper analyzes the formation mechanism of Xinkou landslide, which is considered to be bedding-pushing landslide. The transfer coefficient method is used to calculate and analyze the landslide. It is considered that the landslide is currently in an unstable state and is easy to lose stability and slide under the action of rainstorm or continuous rainfall. On this basis, the paper puts forward the route optimization proposal that the route moves to the left to raise the longitudinal slope to fill through the front edge of the landslide.
