Abstract: Based on the finite element stress-strain analysis, the factor of safety of the slip surface is defined as the ratio of the critical shear intensity during failure to real shear stress, the authors utilize pattern search method to ascertain the critical slip surface of slope. Under the plane strain and homogeneous soil condition, this method is used to analyze the stability of embankment and excavation slope; and the result is compared with natural slope. It is shown that the shape of critical slip surfaces of the three kinds of slopes are similar; the factor of safety of natural slope is higher than the others. At the same time, the result of finite element method is compared with that of limit equilibrium method. Finally, the effect of soil parameters on the stability of embankment and excavation slope is analyzed.

Key words: finite element stress-strain analysis, factor of safety, slip surface, embankment slope, excavation slope
