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。
In this paper, the three-dimensional boundary element finite element coupling method is used to discuss the interaction between spatial structure and non-thick foundation and foundation. The results show that this method can save a lot of computer memory compared with common finite element method when the calculation accuracy is constant, and thus can be used in small size. To analyze spatial interaction problems.
