| 摘 要： | 以鄂尔多斯高原玻璃沟堆积体滑坡为研究对象，从工程地质和数值分析角度对形成机制及稳定性展开研究。研究表明:滑坡目前处于不稳定状态，暴雨、地震等极端工况下极易失稳；降雨和地表水汇集入渗是导致滑坡失稳的直接诱因；玻璃沟滑坡为牵引式多级滑动。

Stability Analysis of Accumulation Landslide under the Condition of Multistage Sliding Surface |
| |
| Abstract: | Taking the Boligou landslide in Erdos Plateau as the research object, the formation mechanism and stability of the landslide are studied from the perspective of engineering geology and numerical analysis. The main conclusions are as follows: the landslide is in an unstable state at present, prone to instability under extreme conditions such as rainstorm and earthquake. Groundwater accumulation and rainfall infiltration are the direct inducement of landslide instability. Boligou landslide is a traction multistage slide. |
