| 摘 要： | 滑带土强度参数的的正确选取，是滑坡稳定性评价及滑坡治理工程设计中的关键问题。分析了滑带土的结构强度特征，提出了滑带土残余强度与再生强度的不同使用场合。通过对滑坡稳定安全系数的定义讨论，明确了滑坡稳定安全系数及滑带土强度参数的物理涵义，提出了滑带土强度参数的取值方法。最后，结合古树包滑坡实例，研究了滑带土强度参数的取值。

| Abstract: | The strength parameters of soil in slide zone are indispensable factors for stability evaluation and control design to a landslide. In this paper, the strength characteristics of soil in slide zone are analyzed, and the residual strength parameters and the restorative strength parameters of the soil in slide zone are discussed, too. The implication of the stability safety factor for landslide and the strength parameters of soil in slide zone is gotten clear through discussion about the definition of the stability safety factor for landslide. The method of determination of the strength parameters of soil in slide zone is proposed. Combined with the practice of Gushubao landslide, the strength parameters of soil in slide zone are determined. |
