STUDIES ON SOME ISSUES OF SEISMIC RESPONSE ANALYSES FOR SUBMERGED TUNNEL
沉管隧道地震响应分析若干问题的研究

The high-speed-railway in Nanjing Changjiang Tunnel is taken as example to study the effects of the ground damping ratio,the ratio of ground rigidity to tunnel rigidity and intersegmental coupling form of tunnel on the tunnel earthquake response. The study module consists of spring and mass in the analysis of earthquake response. Some useful conclusions are presented.
