摘    要:文中分析了土体屈服准则的种类、强度折减法的原理,并结合实际算例说明有限元强度折减法不需任何假定,通过强度折减即可较为精确地计算边坡的安全系数以及边坡处于极限状态时潜在的滑动面,说明有限强度折减法是进行边坡系统分析的一种有效方法。

关 键 词:边坡稳定  有限元强度折减法  滑动面

Abstract:The different soil yield criterions and the principle of strength reduction finite element method(FEM) are thoroughly analyzed.Then combined with practical work to explain it we don't need any assumption,and it could calculate the safety factors and the potential slip surface in the extreme state of slope exactly,that means if we use the strength reduction FEM to analyze slope stability,then itcan be applied.
Keywords:slope stability  strength reduction FEM  slip surface
