摘要
上海轨交17号线徐泾北城站交通枢纽及其配套设施项目因有建设中的轨交17号线高架线路穿越,故在交通枢纽及配套设施施工过程中需对轨交高架段进行保护。介绍了大跨度地铁保护模架体系的设计方案并对其承载力进行了计算。计算结果显示,该模架体系完全能满足使用要求,且模架体系安装方便、高空作业少,使用过程安全,与轨交施工不冲突,具有良好的施工适应性。
Because of Shanghai Rail Transit Line 17 passing through the transportation hub of Xujing North City Station and auxiliary facilities, the elevated section of the rail transit line needs to be protected during the construction of transportation hub and auxiliary facilities. This paper introduces the design scheme of large-span subway support framework system and the load calculation. The result shows that such formwork system can completely meet operating requirements. Besides, it is easy to install, and has less overhead operation. In addition, it is safe in operation process, without any conflict with rail transit construction, and has excellent construction adaptability.
