| 摘 要： | 联络通道与盾构隧道的连接处是隧道抗震的薄弱环节,但目前有关联络通道抗震性能的研究开展得还很少。对于隧道与联络通道连接部位这类典型的空间结构,三维动力有限元分析是最为有效的方法,而其中的人工边界条件和地震动输入方法是实现这一方法的关键技术之一。本文以显式形式将多次透射边界条件引入三维动力分析控制方程,采用分割算法分别求解边界节点和内部节点的响应,然后以对武汉长江隧道工程为背景,利用这种算法研究了隧道与联络通道连接处的地震响应规律,并对采用柔性搭接代替刚性接头和地基加固两种措施的减振效果进行了计算分析。 |

| Abstract: | The joints between the connectional passages and the shield tunnels are weak links in earthquake,whereas little correlative research has been done so far.The most effective approach for such typical spatial structure is to simulate the whole soil-structure interaction system by finite element method.In this thesis,we introduced the multi-transmitting boundary into the dynamic governing equation with an explicit form and presented a partitioned solution procedure,which solved the responses of boundary nodes ... |
