摘    要:基于岩质边坡滑动面和稳定性主要由岩体结构面强度决定的实际,作者首先采用有限元应力分析方法估算了岩体结构面的稳定安全系数,进而利用有限元强度折减法对岩质边坡稳定性进行了数值模拟研究。研究结果表明,采用有限元应力分析方法和强度折减法相结合的方式能快速有效地求解岩质边坡的稳定安全系数,并可为岩质边坡稳定性评价提供一定的指导依据。

关 键 词:岩质边坡  稳定性  有限元法  稳定安全系数  数值模拟

Abstract:The authors first used the finite element stress analysis method to estimate the stability safety factor of a rock mass shearing plane and then made a numerical simulation study of rock slope stability by using the finite element strength reduction method based on the fact that the sliding surface and stability of rock slope are mainly determined by the shearing plane strength of rock mass.The study results show that the stability safety factor of the rock slope can be obtained in a quick and effective way by using the finite element stress analysis method in combination with the finite element strength reduction method,which can provide certain basis for evaluation of rock slope stability.
Keywords:rock slope  stability  finite element method  stability safety coefficient  numerical simulation
