| 摘 要： | 北江大堤石角段堤基为强透水深砂层，是经常出险情的堤段．根据该堤段的地形地质情况，以测压管资料作为依据，反求出二维渗流分析的边界条件，通过有限元计算得到与实际情况相符的结果，也与三维数值计算结果一致

| Abstract: | The foundation in Shijiao section of Beijiang levee is formed by strongly permeable deep sand deposits, which is often in danger. The boundary condition of 2 D seepage analysis was determined according to the topography and geology of the levee and the data of the piezometers. The result being consistent with the reality by means of finite element method was obtained. It is also consistent with the 3 D numerical result. |
