| 摘 要： | 毕威高速K103＋240～580段路基开挖中边坡出现滑坡。从地形地貌、地层岩性、地质构造、气象水文和水文地质方面查明滑坡的区域环境。并勘查滑坡的边界条件、形态特征、结构特征和变形破坏特征。在此基础上,讨论边坡变形破坏的成因机制,对边坡稳定性进行定量与定性评价。并依据这些研究和地质条件提出边坡防治建议。 |
| 关 键 词： | 毕威高速公路 滑坡 成因 稳定性 防治建议 |

| Abstract: | Landslides occurred during the roadbed excavation of Segment K103 +240~580.The regional environment was identified in terms of topography,lithology,geological tectonics,meteorology,hydrology and hydrogeology.We also investigated the boundaries,morphology,structure,deformation and failure characteristics of the landslides.On this basis,we discuss the causes of the slopes’ deformation and failure mechanism,evaluate its stability both quantitatively and qualitatively,and finally offer our control recommendations here. |
| Keywords: | Bi-Wei Expressway landslide cause stability control recommendation |
