| Abstract: | The numerical method of slip lines to analyze the stability of slops is presented by combining finite elememt method, theory of limit equilibrium and numerical analysis method of ordinary differential equation. In NMSL, the stress-strain relationships of soils and the failure forms of instable slops are considered. Beginning at the analysis of variation of stress distribution of a slop, the location of critical slip surface is directly determined, and the globe safety factor is calculated. |
