| Abstract: | Fundamental theories of slope stability analysis by finite element method are introduced systematically. Safety index and judging criterion are discussed in detail; and related visual analysis software AFEAS is developed by object-oriented technique. An engineering example of slope stability analysis is given; related finite element analysis results are compared with results of rigid body limit equilibrium method. Analytical results verify safety index and judging criterion feasible and show advantages of analyzing slope stability by finite element method. |
