-
摘要: 本文用三维边界元有限元耦合法讨论了空间结构,非厚大基础与地基的相互作用问题,结果表明该方法在计算精度不变时可比普通的有限元法节省大量的计算机内存,从而可用小型机来分析空间相互作用问题。Abstract: In thispaper, the coupling method of three dimensionl BEM and FEM for analysis of the interaction between space structure and foundation soil is studied, the results indicate that this method can save a great quantity storages of computer than original FEM with the calculating precision not change. Using the mcthod of this paper, the space interaction problem could be solved with miniature computer.
