T he analysis necessity,common research methods,advantage and disadvantages for seismic dynamic response of crossing metro tunnel structure were elaborated in detail and the finite element numerical simulation was proved to be an effective method to study the problem. Based on Dawang road metro station construction where metro line No.14 under-passing metro line No.1,the research ideas and the detailed implementation steps for seismic dynamic response analysis of crossing metro tunnel structure were introduced by using the ADINA software,which includes geometric modeling technique,processing method of the initial strain,settings of the infinity boundary, correction of earthquake acceleration time-histories filtering and baseline,assumption of seismic dynamic analysis, settings of the analysis variables and value abstraction in seismic analysis.
