| Abstract: | As one of the most difficult topics of rock mass hydromechanics, seepage free surfece plays an important part in slope stability researches. Based on analysis of numerical methods to solve seepage free surface, global composite element iteration (GCEI) is presented in this paper. FEM program is made by using GCEI. Much calculating verifies that not only the program is simpler using GCEI, also the tolerance is higher after 5 iterations. |

| Keywords: | rock mass slope seepage free surface global composite element iteration verification |
