基于有限元计算的公路岩土边坡可靠性分析

Side Slope Reliability Analysis on the Basis of Finite Element Method

将有限元计算与可靠性分析方法进行了有机的结合,建立一种既考虑岩土物理力学参数的随机性,又能反映岩土边坡应力分布规律的边坡稳定性的综合分析方法。利用该方法对边坡稳定性的评价结果与实际相符。

The paper combines the finite element with the reliability analysis method to set forth an integrated analysis system taking into account of physical and mechanical parameters of rock and soil mass as well as distribution of stress in rock and soil mass on road slope reliability.The analysis result of road slope reliability is the same as actual situation.
