| 摘 要： | 针对滑坡的滑动仅使其前缘的挡墙发生位移或变形，但未使之完全破坏的工程实践，系统提出了滑坡前缘的挡墙在发生倾覆、前移和剪切三种变形下，考虑挡墙变形后对滑坡的剩余抗滑作用进行滑带土抗剪强度指标反算的理论和方法。工程实例表明，在滑坡前缘的支挡结构未完全破坏的情况下，滑带土抗剪强度指标的反算只有考虑支挡结构变形后的抗滑作用，才能得出与实际较为符合的结果。

| Abstract: | In view of the engineering practice that retaining wall in the front edge of landslide is only deformed but not destructed completely as a result of the slide of slope, this paper presents a back calculation method of landslide shear strength index considering the residual resistance of retaining wall occurring topple, translation and shear deformation. The project example indicates that calculated results, taking the residual resistance of the deformed retaining wall into account, conform to the practices under the preceding situation. |
