临夏某高速公路互通段滑坡稳定性分析

以临夏某高速公路互通段线路右侧山体滑坡为研究对象，通过对互通段坡体进行划分区域及监测，对地表变形和深孔位移监测结果进行分析，研究已形成滑坡区的变形和破坏机制，并依据监测结果对坡体进行稳定性计算。结果表明:已发生滑坡的A区处于自稳状态，B区滑坡体存在变形且在发生蠕变滑动，滑坡区对邻近坡体的影响较小，两邻近的C区和D区坡体整体处于稳定状态。对A区滑坡体不同位置采取削坡卸载、抗滑桩和支挡等措施，B滑坡区前缘采取填土反压与排水等措施。

Aalysis of Landslide Stability of a Highway Interchange Section in Linxia

Based on the landslide on the right side of the line in a highway interconnecting section in Linxia, through the division and monitoring of the slope body in the interconnecting section, the monitoring results of surface deformation and deep hole displacement have been analyzed, the deformation and failure mechanism of the landslide area has been studied, and the stability of the slope body has been calculated according to the monitoring results. The result shows that the landslide in zone A is in self-stable state, while the landslide in zone B has deformation and creep sliding. The landslide has little influence on the adjacent slope bodies, and the slope bodies in zone C and D are in a stable state. For different positions of landslide body in zone A, measures such as slope cutting and unloading, anti-slide pile and retaining have been taken, and for the front edge of landslide body in zone B, measures such as backfilling and drainage have been taken.
