摘　　要：阐述了地铁交叉隧道结构地震动力响应分析的必要性和常用研究方法及其优缺点,指出采用有限元数值模拟方法是研究此问题的有效手段。以北京地铁14号线下穿1号线大望路站节点工程为依托,介绍了采用ADINA软件研究地铁交叉隧道结构地震动力响应分析的研究思路及其实现步骤,主要包括几何模型的构建、模型初始应变处理、无限远边界设置、地震加速度时程滤波与基线校正、地震动力分析假定以及分析变量设置与数值提取等。The 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.
