摘要
通过诸永高速公路滑坡的现场监测和勘察资料分析,初步确定了滑动面位置。然后假定滑动面原状土与重塑土力学参数比值ξ,反演获得比较符合坡体实际变形情况的滑动面抗剪强度参数。在此基础上,模拟高速公路施工过程中坡脚开挖对边坡稳定性的影响,揭示其变形破坏机理。
The sliding surface of Zhuyong expressway landslide can be initially determined through on-site monitoring and inspection data. An actual shear strength could be obtained by assuming the mechanics ratio ξ of the undisturbed soil to the remolded on sliding surface. Based on this, this paper simulates the foot excavation of slope to study the effect it brings on the stability of the expressway landslide and therefore reveals its deformation mechanism.
