| 摘 要： | 提出一种改进局部安全系数法以考虑土坡渐进破坏过程。该方法是一个涉及搜索危险滑裂面的总体最小安全系数和寻找土条侧面强度发挥系数的最优组合的过程。采用双层MDCP法离散组合型方法解决这一二重优化问题。结果表明，改进局部安全系数法较之以常规方法更合理、高效。

| Abstract: | An improved method considering variable factor of safety is proposed to describe the progressive failure process of soil slopes. The proposed method includes finding the minimum general safety factor of critical slip surface and searching the optimal combination of the intension factors of the intercolumn. The double MDCP method was applied to solve the optimal problem. It is concluded that the improved method is more reasonable and more efficient than the common ones. |
