| Abstract: | Yield mechanism of simplified slip line surface is set up.With energy method based on theory of plastic potential energy in plastic mechanism,the formula of the safety factor for stability analysis of soil slope is deduced.Analysis for an engineering example shows that energy method based on yield mechanism of simplified slip line is reliable.Without searching critical slip surface,the method is convenient for elementary stability analysis of homogenous soil slope. |
