摘要：
The shear strength of unsaturated soil will be increased due to matric suction, which is effective stress. According to Fredlund's shear strength theory of unsaturated soil, the matric suction on the inter-slice and the base surface of slice is considered in the limit equilibrium analysis of slope at the same time. An objective function based on limit equilibrium analysis is created and is applied to seeking most hazard failure plane with the sequence of linear programming (SLP) optimization method. An example of engineering is given, it is shown that the analytical idea in this paper exerts an influence on the stability evaluation of slope.
