Dynamic Analysis of Esfahan Metro Tunnels

A. Bagherzadeh and B. Ferdowsi

This study discusses the modeling of Esfahan metro tunnels subjected to earthquake and interaction of tunnels. In critical structures like subway tunnels, performing a time history dynamic analysis is the only acceptable method for determining the seismic-induced forces. For sites with no recorded earthquake ground motion, artificially generated accelerograms to represent the real earthquake records has been suggested by many experts. This study addressed the modeling of metro tunnels subjected to earthquake with finite difference numerical model. FDM model is developed to estimate the long-term support system. The numerical results of obtained in this research were compared with the analytical solutions. The analytical procedure in this study is limited in scope; it appears to be useful for a preliminary design of tunnel linings to estimate the seismic effect.
