摘　　要：针对常规地铁线路设计方法在建(构)筑物密集地段无法解决拆迁量大、施工难度大、风险大、代价大等问题,创新一种特殊交叉渡线加曲线岛式错位站台组合的线路设计方法,不仅能满足建筑、结构、信号、轨道、行车、线路等相关专业的设计需求,而且能使得地铁线路可以灵活地绕避站点周边密集的建(构)筑物。研究结果表明:该创新线路设计方法可以实现减少拆迁、加大施工净距、缩减明挖规模、降低施工难度和风险、节省工程投资等目标,为地铁站点周边建(构)筑物密集、拆迁和施工困难的地段提供技术指导。通过实际的工程案例验证,表明该创新线路设计方法能产生很好的经济、技术和社会效益。The conventional subway line design method cannot address the issues of a large amount of demolition,complex construction,high risk,and high cost in the densely built areas under construction.This article innovates a line design method that combines a special scissors crossover with a curved island-type misaligned platform,which not only meets the design needs of related disciplines such as architecture,structure,signal,track,train operation,and line but also allows subway lines to avoid dense buildings around the station flexibly.The results indicate that this innovative route design method can reduce demolition,increase construction clearance,reduce open excavation scale,reduce construction difficulty and risk,and reduce engineering investments.It provides technical guidance for areas with dense buildings,as well as demolition and construction difficulties around subway stations.The application to practical engineering cases demonstrates that this innovative line design method can yield economic,technical,and social benefits.
