Seismic Dynamic Response Study of Wuhan Changjiang River Tunnel
This paper presents seismic dynamic response rules of Wuhan Changjiang River tunnel. Bilateral seismic dynamic responses of tunnel typical geology section are studied based on software of ANSYS. Conditions of gravity and water pressure are considered compared with that of no gravity. Some conclusions have been obtained:(1)The node displacement of lining arch crown is the biggest, which of soffit lining is the least under two-way earthquake. The maximal node displacement not considering initial condition of gravity decreases 34 percent, and the relative displacement reduces 22 percent between the top and the bottom of lining compared with thinking of gravity influence; (2) The maximal equivalent node stress of the former distributes on lining side wall, which decreases 29.4 percent in comparison with the latter under two-direction earthquake;(3) The gravity factor can not be ignored in seismic analysis of underground tunnel.
