| Abstract: | In this paper,3-D slope stability analysis has been conducted with the Modified FEM GIM through Ansys--a large-scale finite element analysis software,and the obtained results are compared with results gained through SRM.The comparison shows that the Modified FEMGIMhas ideal accuracy,and it can be concluded from the results that the modified GIMis applicable and flexible in 3-D slope stability analyses.And this method have certain instructive significance to engineering practice. |
