边坡安全系数求解是边坡稳定性问题分析中的主要问题,强度折减法在边坡稳定性分析中运用越来越广泛。利用FLAC3D软件进行数值模拟,选择弹塑性Mohr-Coulomb模型及其破坏准则,通过对算例结果进行比较表明:强度折减法能够真实地反映边坡的实际情况,方便合理,求得的边坡安全系数接近实际,显示出其在边坡稳定性分析中的一定优势。

Safety factor solving is the main problem of slope stability problem,and the use of strength reduction method in slope stability analysis is more and more extensive.FLAC3D in numerical simulation is used and choose plastic Mohr-Coulomb model and failure criteria is chosen.Bycomparison the results show that： Strength reduction method can truly reflect the actual situation of the slope,facilitate to get reasonable safety factor of slope and be close to the reality...
