| 摘 要： | 基于对滑坡稳定性影响强烈的岩土性质、计算模式、地下水及荷载等因素的分析,建立滑坡稳定性评价的极限状态方程,通过对岩土参数、地下水及有效重力等敏感因子的求解及分布特征分析;在对泰勒级数对非线性极限状态方程线性化后,结合结构可靠度的理论,运用一次二阶矩的方法,求解了滑坡稳定性可靠度指标β,最后通过开县康家咀滑坡稳定性对比分析,证明了该方法的正确性,提高了滑坡稳定性评价精度.

| Abstract: | Based on analysis of affecting factors of landslides stabilization,in this article the limit state equations have been set up.Then,through parameter analysis of landslides stabilization's affecting factor combined with reliability method,making use of First-order Second-moment method,the reliability index is applied with landslides stabilization analysis.At last,this theory is checked through contrast analysis on the stabilization of Kangjiazui landslide in Kaixian. |
