摘要
对土工合成物加强软土地基，目前仍用圆弧滑动法分析其稳定性。本文根据极限分析的原理，判定圆弧滑动不是一种可能的破坏方式，只有侧向挤出才符合真实的破坏机理，并在此基础上提出一种基于滑块平衡的简便分析方法。
The stability of soft ground reinforced by geosynthetics is currently analyzed by conventional circular arc method.In this paper it is confirmed that the circular arc slide is not a kinematically admissible failure mode,and the only possible way of failure of the reinforced ground is lateral spreading of soil under the geosynthetic layer.Accordingly,a simple wedge equilibrium method has been proposed for the design of such ground.
