摘要
ANSYS软件是由美国SASI公司开发的世界最著名的大型通用有限元分析软件,它不断吸收当今计算力学与计算机技术的最新成果,使其在FEA(有限元分析)领域稳居霸主地位.将强度折减法应用于边坡稳定性分析中,折减土体强度,代入有限元程序进行计算,直至计算不收敛,此时的折减系数即为安全系数.结合工程实例,对比强度折减法的边坡稳定性有限元法和传统极限平衡法的计算结果,表明ansys基于强度折减法的边坡稳定性有限元分析应用与工程实际是可行的.
The soft of ANSYS is invented by SASI company and known as the most famous soft of structural analysis.It consistently adopts the latest output of calculation mechanics and the technology of computer.As a result,it is always in the position of leade in the field of FEM.By using the strength reduction method in the analysis on slope stability,the soil strength is reduced,so that the numerical non-convergence occurs,and the safety factor is obtained.With a case study,the result analyzed by the traditional method is compared with that by strength reduction FEM.It is indicated that the slope stability analysis of ANSYS is appropriate based on strength reduction method..
