Seismic Response Analysis of Connectional Passage in Twin-Tunnel Based on Parallel Computing

Abstract

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
