摘要
讨论了用有限元与边界元耦合方法求解地下结构的弹粘塑性问题；对临界状态模型推导了用于隐式计算格式的 Ｈ矩阵的显式表达式。文中最后计算了两个应用实例，并与弹塑性分析结果进行了比较。
The paper comprehensively discusses a numerical method of solving elasto-viscoplastic problems of underground structures by coupling the finite elements with the boundry elements. For critical state model, the author derives an explicit formula of matrix H, which is used in implicit computation scheme. Finally, two practical examples are examined and compared with elasto-plastic analysis results.
