基于强度折减有限元法的边坡稳定分析
Study on Criteria for Evaluating Stabil ity of Slope with FEM
目前，判别边坡失稳的依据没有一个统一的标准，本文在前人研究的基础上。采用有限元强度折减法，把计算的收敛性、特征部位位移的突变性和塑性区的贯通性作为失稳判别准则。借助ADINA有限元软件对典型算例进行了稳定分析，得出了有益的结论。
Based on shear strength reduction methods, a rational and practical criterion to judge the safety factor of slope is proposed. That is the convergence of equation’s solution, the abruptness of the displacement or deformation at a certain characteristic location and the connectivity of plastic zone. In the presence of FEM software ADINA and this criterion, an example slope is analyzed. Some important conclusions are obtained.
