摘　　要：在流砂土层中的管道投入使用后,管道自身及周边的土层处于一种平衡的状态。但进行管道迁改会给周边的土体带来扰动,破坏原有的平衡状态。为保证原有设施的正常运行及工程项目的实施,需综合考虑多方面因素。结合无锡市南泉古镇现状污水管道迁改工程,介绍了流砂土层中管道迁改的技术问题与处理措施,供类似工程参考。The pipeline and its surrounding soil are in a state of balance after it is used in the quicksand layer. But when the pipeline is relocated, it will bring disturbance to the surrounding soil and the original balance will be destroyed. In order to ensure the normal operation of the original facilities and the smooth implementation of the project, many factors should be comprehensively considered. Combined with the sewage pipeline relocation works in Wuxi Nanquan town, the technical problems and measures of the pipeline relocation in quicksand layer were introduced, which provides a reference for similar pro- jects.
