摘要

非饱和土基质吸力的有效应力作用，使得土体的抗剪强度得以提高。基于Fredlund的非饱和土抗剪强度理论，在土坡极限平衡分析方法中，同时考虑分条的土条底面与条间的基质吸力分布对土体抗剪强度的贡献，进而构筑考虑基质吸力作用的土坡极限平衡分析方法。构筑基于极限平衡分析方法的目标函数，应用SLP优化方法寻求最危险滑动面。用具体计算实例说明这种分析思路可以评价土坡的稳定性评价的影响。

Abstract

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.
