| 摘 要： | 将强度折减理论应用于边坡稳定性分析中,借助FLAC/SLOPE有限差分分析程序,选择弹塑性Mohr-Coulomb模型及其破坏准则,以大唐略阳电厂边坡作为工程实例,分析了该边坡的稳定性,并与传统的Bishop法、Janbu法等方法计算所得边坡稳定系数进行了对比分析。结果表明,有限差分强度折减法能更加真实地反映边坡的实际情况,求得的边坡稳定系数更接近边坡的实际稳定状态,显示出其在边坡稳定性分析中的一定优势。

| Abstract: | The stability of a slope in Datang Lueyang Power Plant is analyzed.This study adopts the strength-reduction theory,FLAC/SLOPE finite-difference program,elastic-plasticity Mohr-Coulomb model,as well as its failure criterion.The stability factors obtained from the study are compared with those obtained through the conventional Bishop and Janbus’ methods of slices.The results show that the finite-difference and strength-reduction method is more convenient and reasonable in the analysis of slope stability.It can reflect the actual slope state,and give stability factors that are closer to the actual ones. |
