摘　　要：结合采用顶管技术施工的某水厂出厂管道工程,通过对沉井法和逆作法施工的两口规格相同的工作井和接收井,从设计、施工工艺、工期进度、费用成本角度出发进行全方面分析,阐述了两种施工方法在实际应用中的优点以及存在的问题。通过对比分析,得出施工条件允许的情况下逆作法施工的优势要大于沉井法,为水厂出厂管道工程后续井位施工方法的选取提供了理论依据,也为相关类似工程提供了参考建议。Two working wells and receiving wells of the same specifications were constructed by shaft digging method and topdown construction method in combination with pipe jacking technology in a water plant pipeline project.The advantages and problems of the two construction methods in practical application are expounded from the perspective of design,construction technology,schedule and cost.Through comparative analysis,it is concluded that the advantage of topdown construction method is greater than that of shaft digging method under permitted conditions,which provides a theoretical basis for the selection of subsequent well location construction method of pipeline engineering of water plant,and also provides reference suggestions for related similar projects.
