摘　　要：以济南西客站站台下的地铁隧道为研究对象,重点研究高铁荷载作用下地下结构的动力响应。列车高速移动时伴随着振动,所以既要考虑荷载的移动,也要考虑荷载的振动。首先应用移动问题有限元方法计算移动放大系数,然后应用ABAQUS软件分析振动荷载作用时高铁站台下地铁隧道的动力响应,并给出了一些数值算例。The article took the Jihan West Railway Station subway tunnel structure as a project background and studied dynamic responses of underground structures produeed by high-speed train loads. Due to vibra- tions induced by high-speed trains, both moving loads and vibration loads were considered. The moving fi- nite element method was firstly used to ealeulate the moving amplifieation eoeffieient. Dynamie responses of the subway tunnel were analyzed by using the ABAQUS software. Some numerical examples are provided.
