摘　　要：对于主要城市的主城区以及土地征用紧张的地区,桥下式站房作为一种常见的客站布置形式,具有桥下空间利用率高、节省建设用地、方便旅客进出站,高效便捷出行等良好的特点,但其建筑及结构设计也受限于桥梁跨度及桥下空间高度的影响。为充分利用高架桥梁的桥下空间进行车站结构设计,文章结合北京大兴站、密云站及新绍兴北站等3座站房的工程实例,对该类桥下式站房的结构设计进行总结分析,阐述该类站房的结构设计原则,在不同设计条件下,为站房基础、结构选型、单元划分、抗震设计等方面提供有益的设计思路和方法。结果表明:结合桥下空间特点及建筑布置要求的车站结构设计可实现“小震不坏、中震可修、大震不倒”的抗震设防目标,达到保证主体结构安全与车站建筑功能要求的统一,桥上线路设计与桥下空间利用的统一,和社会效益与经济效益的统一。For the main urban areas of major cities and areas with tight land acquisition,as a common form of passenger station layout,the under-bridge station building has the characteristics of high utilization rate of space under the bridge,saving construction land,convenient for passengers to enter and exit the station,efficient and convenient travel,etc but its architectural and structural design are limited by bridge span and height of the space under the bridge.In order to make full use of the space under the viaduct for the structural design of the station,the structural design of the under-bridge station building is summarized and analyzed by combining the engineering examples of three station buildings,including Beijing Daxing station,Miyun station and New shaoxing North Station;the structural design principles of this kind of station building is expounded;so their useful design ideas and methods can be used for reference at station foundation,structure selection,unit division,seismic design and other aspects under different design conditions.The results show that the design for station structure not only can achieve the seismic fortification goal of"no damage in small earthquakes,repairable in medium earthquakes,and no collapse in large earthquakes"combined with the characteristics of the space under the bridge and the requirements of the building layout of the station,but also can achieve the unity of ensuring the safety of the main structure and the functional requirements of the station building,the unity of the line design on the bridge and the utilization of the space under the bridge,and the unity of social and economic benefits.
