摘　　要：市政管线迁改是地铁建设的主要影响因素,如何提高其设计效率与技术水平是地铁设计的重要问题。以成都地铁6号线为背景,在典型站点管线迁改方面,摸索出结合站点工法分期迁改的方法,形成标准化成果;在特殊的高风险管线迁改方面,结合实际条件提出不同的创新解决方案并得以实施,涵盖运营中高压电力隧道分节移动方案、大断面污水渠与锦江河堤结构同体方案以及大管径燃气管线在地铁站半盖挖工法中原位保护方案。设计方案为高效推进地铁建设提供了保障,可以为类似项目提供参考。The relocation of the municipal pipeline is a critical factor in subway construction.Enhancing the design efficiency and technical proficiency of pipeline relocation is a significant concern in subway design.Regarding the pipeline relocation for metro line 6 in Chengdu,a phased relocation approach for station construction was determined,and a standardized methodology for improving the design efficiency was established.Regarding the relocation of special high-risk pipelines,various innovative solutions were developed and implemented based on specific conditions.These included the segmented movement plan of an operating high-voltage power tunnel,the scheme of large-section sewage channel and the Jinjiang River embankment sharing the structure,and the scheme of in-situ protection of large-diameter gas pipelines during the half-cover excavation method adopted by the subway station.The design scheme facilitated the efficient advancement of subway construction.Therefore,it can serve as a valuable reference for similar projects.
