摘　　要：在城市轨道交通施工过程中,地下埋设有电力、电信、燃气、雨污水、给排水等多种管线,走向复杂,若处理不当会给施工带来很大的危险。一般情况下,施工前会对管线进行迁改处理,但对一些无法迁改的管线,需进行悬吊保护处理。论文通过工程实例,介绍超大直径排水管悬吊梁设计及基坑围护结构的受力计算,提出相应的质量控制措施,为相关工程提供参考。In the process of urban rail transit construction, much pipeline are buried underground,such as electricity, telecommunications,gas, rain and sewage, water supply and drainage and other pipelines, which will bring great danger to the construction if not handled properly. In general, the pipeline will be relocated before construction, but some pipelines that can not be relocated need to be suspended and protected. This paper introduces the design of suspension beam of large diameter drainage pipe and the stress calculation of foundation pit retaining structure through engineering examples, and puts forward the corresponding quality control measures to provide reference for related projects.
