宜巴高速公路老屋包滑坡成因分析及治理设计

Cause Analysis and Treatment Design of Laowubao Landslide on Yiba Highway

以宜巴高速公路老屋包滑坡高填方路基工程为例,根据不同施工阶段变形监测数据,研究了高速公路工程不同方案对滑坡稳定性的影响。结果表明:老屋包滑坡前缘采取高填方路基工程可有效控制滑坡变形,提高滑坡稳定性。

The high-filled embankment of Laowubao landslide of Yichang-Badong expressway is taken as an example, the settlement and deep displacement monitoring during the construction of were carried out, and then the effect of different schemes of expressway engineering on landslide stability is studied. It shows that the high-filled embankment adopted at the front of Laowubao Landslide can effectively control landslide deformation and improve landslide stability, which can provide a reference for similar project.
