摘要： 以上海某大型双线隧道为例，考虑隧道地基的动态接触作用，建立了隧道联络通道地基系统的大型三维有限元模型，采用接触均衡的显式并行计算方法在上海超级计算机曙光5000 A上完成计算，解决了计算量大的问题，分析了联络通道处结构及变形缝在横向和纵向水平地震激励下的动态响应，结果可为联络通道和变形缝设计提供参考.

Abstract:  Considering the dynamic tunnelsoil interaction, a large-scale three dimensional finite model of tunnelconnectional passages-soil was established for a twin-tunnel in Shanghai. The model was solved on Dawning 5000 A in Shanghai Supercomputer Center based on contact balanced algorithm for explicit parallel computing. The dynamic responses of connectional passages were analyzed and the results can provide references for the design of connectional passage and deformational joint.

Key words: twin-track tunnel, connectional passage, seismic response, parallel computing, 3D finite element, numerical simulation
