摘　　要：对合肥新桥国际机场旅客过夜用房的基本结构体系及其与地下轨道交通结构的关系进行介绍,对无控及有控条件下旅客过夜用房在轨交激励下的楼层振动进行了评估,确定楼板需要隔振。围绕振震双控基本设计思路、隔振支座布置流程、限位支座设计理念等展开讨论,并对竖向振动隔离条件下的结构抗震性能进行分析。结果表明,采用钢弹簧隔振器和限位装置后,结构满足规范对振动及二次辐射噪声的限值要求,同时隔振条件下的结构抗震性能可以得到保证,从而实现振动、地震双重控制。The basic structural system of the overnight passenger accommodation of Hefei Xinqiao International Airport and its relationship with the underground rail transit structure were introduced.The floor vibration of the overnight passenger accommodation under uncontrolled and controlled conditions was evaluated,and it was determined that vibration isolation is required.The basic design ideas of vibration-seismic dual control,the arrangement process of vibration isolation supports,and the design concept of limiting device were discussed,and the seismic performance of the structure under vibration-isolation conditions was analyzed.The results show that after the steel-spring isolators and limiting devices are used,the structure meets the requirements of the code for vibration and secondary radiated noise.At the same time,the seismic performance of the structure under vibration-isolation conditions can be guaranteed,thereby achieving the dual control of vibration and seismic.
