| 摘 要： | 本文依据地下巷道衬砌(或支护)与围岩的相互作用关系,将边界元域的所有未知量全部凝聚到耦合面上来实现有限元与边界元的耦合数值计算,并且对耦合计算中所能遇到的奇异性问题进行了讨论,给出了求解的途径,文末还对两个工程实例进行了计算研究。

| Abstract: | Based on interaction between roadway liner and surrounding rock, this paper uses a method of condensing all the unknowns in domain of BEM ( Boundary Element Method ) to coupling surface to carry out the couple between FEM ( Finite Element method ) ) and BEM. It also discusses the cause of sigularity on the coupling surface, and presents a way for solving this difficulty. Finally, two practical examples are studied by this coupling method. |
