摘　　要：依托南京惠民大道综合改造工程,针对典型地下互通空间结构在地震作用下的动力响应问题展开研究,采用有限元法模拟计算,建立含夹空层隧道结构体系下的工程简化模型,对含夹空层隧道结构体系进行抗震性能分析,并研究该体系条件下的含夹空层开发利用可能性。针对具体夹空层结构的抗震性能提出有效的抗震措施,该方法可为相似类型工程的空间规划提供有益的参考。Relying on Nanjing Huimin Avenue Comprehensive Reconstruction Project, the dynamic response of the typical underground interconnected space structures under earthquake is studied. The finite element method is used to simulate and calculate. The engineering simplified model under the sandwich layer-tunnel system is established to analyze the seismic performance of sandwich layer-tunnel structure system. And the possibility of development and utilization of the sandwich layer under the condition of this system is studied. The effective seismic measures are proposed for the seismic performance of the sandwich layer structure. This method can provide a useful reference for the spatial planning of the similar projects.
