摘要
对边坡稳定性的极限平衡法与有限元方法进行了对比分析,并将这两种方法相结合考察边坡的稳定性,这是边坡稳定性分析的一个重要发展方向。根据有限元计算得到的近似真实应力场,利用数学手段(如动态规划法)计算得到边坡的最小安全系数及其相应的临界滑裂面的确切位置,还有待推出较成熟的商业计算软件。
The theory and characters of the limit equilibrium slice method and the shear strength reduction（SSR） FEM used in slope stability analysis have been studied by comparison analysis in this article. It can be found that combining the limit equilibrium slice method with finite clement method is an important tendency in slope stability analysis. Therefore, based on the approximately real stress field got from FEM, the minimal safety factor and corresponding position of critical slide surface can be got using limit equilibrium method concept through mathematical method（such as dynamic programming method）. It needs to develop common software for this method.
