| 中文摘要 | 近半个世纪以来,有限元方法作为一种有效的数值计算手段已经广为认可,但关于有限元的作用总是存在争议,对有限元的计算结果也常常存有疑虑。对有限元在加筋土结构设计中的应用进行探讨,介绍了加筋土计算中常用的筋土接触面处理方法。以有限元在加筋高边坡设计、基坑位移分析中的作用为例,论述了其应用的必要性,从专业教育、商业软件和社会认识发展等方面探讨了有限元应用的可行性,也对有限元应用中应当注意的问题提出了建议。; The finite element method( FEM) has been widely recognized as an effective means of numerical simulation for nearly half a century. However,there was always controversy over the role of FEM and doubts about the results of finite element calculation. In this paper,application of the finite element method in reinforced soil structure was investigated,and the commonly used simulation methods for the interface between soil and reinforcement were presented. The necessity of using FEM was demonstrated in the design of high reinforced soil slope and the analysis of foundation pit displacement. The feasibility of its application was also discussed in terms of professional education,commercial software development and social awareness. Suggestions on the application of FEM are also presented. |
