摘　　要：[目的]北京地铁国贸站换乘已不能满足当前客流需求,存在较大安全隐患,有必要结合周边商业建筑研究该站的换乘一体化改造方案。[方法]从安全性、舒适性、便捷性、可行性4个方面分析了既有地铁换乘面临的问题,针对既有问题,基于将地铁换乘改造与周边商业建筑改造更新需求相结合的改造思路,提出不同的改造方案。经比选,选择新建通道+新建换乘大厅方案的换乘一体化改造方案作为实施方案。详细阐述了实施方案的设计要点,对实施方案的火灾和疏散情况进行了消防模拟,针对工程施工重要风险点,提出了工程保护措施。[结果及结论]北京地铁国贸站换乘一体化改造方案结合了周边商业改造升级的需求,提高了地下空间一体化程度,使得换乘的舒适性、安全性及便捷性均大幅提升。消防模拟结果验证了一体化改造方案的消防安全性。对新建通道与既有结构的连通,提出了“超前注浆加固先行、初衬优先封闭、停运期间实施”的措施;对下穿的既有桥梁,提出“主动注浆预加固、被动支顶”的加固措施。[Objective] The transfer system at Beijing Subway Guomao Station can no longer meet the current passenger flow demands and poses significant safety hazard.It is necessary to study an integrated transfer renovation scheme for the station that takes surrounding commercial buildings into account.[Method] Problems faced by existing subway transfer are analyzed from four aspects:safety,comfort,convenience,and feasibility.Regarding existing issues,different renovation schemes based on renovation idea by combining subway transfer renovation with the renovation and renewal needs of surrounding commercial buildings are proposed.After comparison,the integrated transfer renovation scheme of the new channel+new transfer hall is selected as the implementation scheme.Its design points are elaborated in detail,and the fire and evacuation conditions of the implementation plan are simulated.Engineering protection measures are proposed for the important risk points in project construction.[Result & Conclusion] The integrated transfer renovation scheme for Beijing Subway Guomao Station combines the renovation and upgrading needs of the surrounding commercial,through enhancing the degree of underground space integration,greatly improves transfer comfort,safety and convenience.The fire safety of the integrated renovation scheme are verified by fire simulation results.For the connection between the newly built passageway and the existing structure,measures of "advance grouting reinforcement first,primary lining priority closure,and implementation during shutdown" are proposed;for the existing bridges passed through by the new passageway,the reinforcement measures of "active grouting pre-reinforcement and passive top support" are proposed.
