Numerical Simulation for Large-Scale Seismic Response Analysis of Long-Distance Water-Conveyance Shield Tunnel
This paper presents a three-dimensional numerical simulation method for large-scale seismic response calculation based on a newly built shield tunnel used for water supply in Shanghai. The whole analytical model consists of surrounding soils, shield tunnel segments, bolts, and many other entities. Both the number of nodes and the number of elements exceed one million. This model could consider dynamic hysteretic nonlinear behaviors of soil, contact interface between soil and tunnel, contact interface between bolts and segments; and the contact interfaces between segments. Final calculation has been performed on the Dawning 4000A supercomputer using the finite-element code LS-DYNA 971 MPP. The result provides a global understanding of this water- conveyance shield tunnel under seismic loading and reveals the weak parts. It also provides relevant data and references for the seismic design of tunnel structure in the future.
