| 摘 要： | 本研究建议的一种分析方法假定斜坡非饱和土体的水分运动参数及剪强度参数与饱和度的依赖关系均可根据实验或经验确定。通过数值计算方法妥任意给定的入渗和蒸发边界条件下斜坡土体的瞬态含水率分布及与其相对应的瞬态抗剪强度参数分布。在此基础上瞬态斜坡安全因数即可通过常规的稳定性分析方法求得。

| Abstract: | This study suggests an analysis method under assumption of that the both soil water movement parameters and shear strength parameters related to the saturated degree can be determined by experiments and experiences. The instantaneous distributions of water content and shear strength parameters can be solved numerically for arbitrarily given boundry condition of infiltration and evaporation. Base on the above, the instantaneous safety factor of slope can be found by use of general methods of slope stability analysis. |
