Abstract
This paper concentrates on using the response displacement method proposed by the current Code for Seismic Design of Urban Rail Transit Structure to conduct two-dimensional lateral seismic calculation.Assumed the same depth,the calculated internal force and deformation of two tunnels located in the site condition Ⅲ under different period horizontal earthquake ground motions.The results by using the dynamic time-history method would be given as reference standard to evaluate the applicability and accuracy of the current response displacement method.When the tunnel is located in a short period seismic motion as a main component of the site condition Ⅲ,the results of stress increment calculated by the response displacement method are slightly larger than those of the dynamic time-history method.Oppositely,the results of stress increment calculated by the response displacement method are slightly smaller than those of the dynamic timehistory method.Besides,the vertical diameter deformation rate by using the dynamic time-history method is much larger than the response displacement method does under a long period seismic motion in the site condition Ⅲ.关键词
