摘　　要：黄土高路堤边坡稳定性验算是西北黄土地区公路建设中的重要问题,也是岩土工程学科中最古老典型的研究课题之一。用有限元强度折减法分析黄土高路堤边坡稳定问题,不仅能直观看出土体应力应变的发展变化,而且可以得出边坡稳定系数。用有限元强度折减法所得出的稳定系数略小于bishop法所得稳定系数。The slope of loess high embankment stability analysis is in northwest loess area highway construction important question, also is in the crag earth project discipline one of most ancient model research topics. This article folds the subtraction analysis loess high embankment stable question with the strength reduction FEM, not only can direct-viewing see the soil body stress strain the development change, moreover may obtain the slope and stability the coefficient. This article folds the subtraction obtained stability coefficient with the strength reduction FEM to be smaller than the bishop law obtained stability coefficient.
