Global Composite Element Iteration to Solve Seepage Free Surface
-
摘要: 渗流自由面是岩体水力学研究的重点和难点,也是边坡稳定性综合研究的重要内容.基于对渗流自由面数值求解方法的分析,提出了复合单元全域迭代法,并编制了有限元计算程序.计算果表明,该法具有程序处理比较简单、计算结果比较精确等特性,一般迭代5次左右便可收敛.Abstract: As one of the most difficult topics of rock mass hydromechanics, seepage free surfece plays an important part in slope stability researches. Based on analysis of numerical methods to solve seepage free surface, global composite element iteration (GCEI) is presented in this paper. FEM program is made by using GCEI. Much calculating verifies that not only the program is simpler using GCEI, also the tolerance is higher after 5 iterations.
