从人文历史调查、地形地貌、地层岩性和地下水条件等方面对该滑坡体的成因机制进行分析,得出某高速公路林家溪路段是一个古滑坡的重要结论,在暴雨及人工开挖条件下可能复活,并对工程建设造成极大影响。对滑坡范围和滑动面位置进行了研究,获取了滑坡稳定性计算模型。最后对滑动面抗剪强度参数进行了室内试验和反分析计算,给出了滑坡体整体稳定和局部稳定的工程治理措施。
The genetic mechanism of this landslide body is analyzed from the aspects of human history investigation, topography, topography, stratigraphy lithology and groundwater conditions. It is concluded that Linjiaxi section of a highway is an important conclusion of the ancient landslide. Under heavy rainfall and artificial excavation It may be revived and have a great impact on the construction of the project. The landslide range and sliding surface location are studied, and the landslide stability calculation model is obtained. Finally, the test and analysis of the shear strength parameters of sliding surface are carried out. The engineering measures for the overall stability and local stability of the landslide are given.
