为了探讨双折减系数法在边坡稳定性分析中的具体应用,依据一工程实例,利用有限差分软件FLAC-3D,采用自编强度折减法求解边坡达极限平衡状态时的不同折减系数组合和相应的安全系数.探讨了采用不同安全系数定义方式对边坡安全系数计算的影响规律,结果表明,双折减系数法较传统折减法更能反映边坡的渐进破坏过程,可为工程技术人员进行边坡设计和施工提供有益参考.%In order to explore the dual reduction factor method in slope stability analysis in the specific application,according to the numerical examples,we obtain different reduction factors combinations and corresponding safety factor when the slope reaches limit equilibrium state by using the finite difference software FLAC-3D.Based on the obtained solution,we investigate the effect of dual reduction factor method on the calculation of slope safety factor.The results show that the dual reduction factor method can reflect the progressive failure process of the slope,and provide useful reference for engineering and technical personnel to carry out slope design and construction.
