摘　　要：在特定地段电缆需穿越京杭大运河施工,尤其在工程地质条件及工程环境均较差的闹市区,为了确保施工期间不影响运河通航,工程难度大,因而采用非开挖电缆管道工艺穿越河底.文章重点介绍了用小型机械进行曲线拖管施工工艺,该施工安排中的关键环节及工艺改进探索.河底曲线拖管施工工艺省内尚属首例,尤其在砂质粉土中施工,难度很大,其经验与教训对类似工程有借鉴意义.Cables in a special section must cut across The Grand Canal in China, especially the construction site is located in the downtown area with relatively poor geological and environmental conditions. In order to be navigable for The Grand Canal in China during the period of construction, the technology of ＂non excavating＂ to cut acrossThe Grand Canal in China was used. The article laid stress on introducing a technology that used small-sized machinery to drag curve pipelines cutting across The Grand Canal in China, key works in the construction organization, and the exploration of the technology improvement. The technology was first to be applied in Zhejiang province, which is extremely difficult to construct in seabeach. The experiences and lessons of this construction are useful reference to other similar projects.
