| 摘 要： | 针对边坡稳定分析条分法存在的问题，在饱和－非饱和渗流不动网格有限元计算的基础上，用土体单元所受的渗透力代替其周边的孔隙水压力，达到利用渗流计算时的剖分网格和计算结果，直接连续进行渗流作用下的边坡稳定分析的目的，并有用数学规划中的单纯形法自动寻找最小安全系数，算例表明，该方法具有一定的实用性，并为考虑降雨等引起的饱和－非饱和不稳定渗流作用下的边坡稳定问题的分析提供了实用的工具。 |
| 关 键 词： | 边坡稳定 条分法 饱和－非饱和渗流 有限元 单纯形法 混合法 等参元 |

| Abstract: | This finite element analysis is directed towards the defects of the general slice method of slop stability analysis. Based on the computation of saturated-unsaturated seepage flow, the seepage force supersedes the pore-pressure around one element to analyze directly and continuously the slop stability with the mesh and results of the seepage finite element analysis. A mathematical optimization technique going by the name of the simple shape method is used to determine the minimal stability safe-coefficient. An engineering application proves its practicability and efficiency. It gives an efficient tool to analyze the slop stability problem caused by the rainfall. |
