Study on seismic behavior and seismic design methods in transverse direction of shield tunnels

摘要

In order to investigate the seismic behavior and seismic design methods in the transverse direction of a shield tunnel, a series of model shaking table tests and a two-dimensional finite element dynamic analysis on the tests are carried out. Two kinds of static analytical methods based on ground- tunnel composite finite element model and beam-spring element model are proposed, and the validity of the static analyses is verified by model shaking table tests.
