摘　　要：结合上海轨道交通6号线工程及轨道交通8号线南延伸段工程,对双线槽形梁现浇法及单线小断面槽形梁预制架设法施工进行了介绍。从施工条件要求、梁体结构施工难度、对周边环境的影响、工期及经济性等方面对两种施工方法进行了系统的比较;分析了各自的优缺点及适用范围,同时对双线槽形梁预制及节段拼装法施工进行了初步探讨,从而为今后城市轻轨工程上部槽形梁的设计选型及施工方法选择提供参考。Based on metro Line 6 and Line 8 south extension project in Shanghai, this paper introduces the casting methods for double- line channel girders and the precast erection methods for single-line channel girders. Both methods are compared from the angles of construction condition requirements, beam structure construction difficulties, environment effect, construction period and economy. The advantages and disadvantages, the applicability of each method are analyzed, the precast-segmental erection methods for double-line channel girders are explored and discussed at the same time, to provide reference for the structure type design and construction method selection in urban light rail project.
