Abstract

As one of the most difficult topics in rock mass hydromechanics, seepage free surface plays an important part in slope stability researches. Based on analysi of numerical methods to solve seepage free surface, global composite element iteration (GCEI) is presented in this paper. FEM program is made by using CGEI Calculation shows that not only the program is simple using GCEI, but also the tolerance is higher after 5 iterations
