摘　　要：提出了一种基于隔震技术的地铁车辆段跨缝设计方案,通过隔震转换的方式实现地铁车辆段盖上结构的开发,有效避免了盖下结构缝对盖上结构造成的限制。在车辆段的顶部设置隔震转换层,并调整隔震支座的布置和参数使盖上结构在跨越盖下结构缝时能够满足温度、地震引起的变形要求,确保结构的安全性和使用功能。以上海某车辆段工程为依托,对所提跨缝技术方案进行研究,结果表明,采用隔震转换的方式可以实现盖上结构的跨缝布置,使盖上建筑的布局更加灵活,有利于地铁车辆段盖上建筑的高质量开发。A design scheme of cross-seam of metro depot based on seismic isolation technology is proposed.Through isolation conversion,the overhead structure of metro depot can be developed,which effectively avoids the limitation of overhead structure caused by the overhead seam.Setting the isolation transfer layer at the top of the depot and adjusting the layout and parameters of the isolation bearings can meet the deformation requirements caused by temperature and earthquake when the cover structure crosses the crack under the cover,so as to ensure the safety and use of the structure.Based on a metro depot project in Shanghai,the research and analysis of the proposed cross-seam technical scheme shows that the cross-seam layout of the cover structure can be realized by adopting the isolation conversion method,which makes the layout of the cover building more flexible,and is conducive to the high-quality development of the cover building in the metro depot.
