摘　　要：以省级筹建输水管道穿越保沧干渠工程为例,比较顶管穿越和水平定向钻穿越方式,确定穿越方式为水平定向钻;介绍水平定向钻平面及导向孔轨迹方案设计、管道回拖力等结构计算、施工技术要求及工程监测方案制定。科学合理的设计成果为保障工程顺利完成提供技术支持,同时对类似工程的设计及施工具有重要意义。This paper takes water pipeline of the provincial preparatory project crossing baocang main canal project as an example, it introduces the basic situation of the project, it compares the modes of crossing between pipe jacking and horizontal directional drilling, and it is determined that the mode of crossing is horizontal directional drilling, it introduces the plane layout project, the design of pilot hole track, the structural calculation of back dragging force and the construction technical requirements, finally, it introduces the monitoring project. The scientific and reasonable design results provide strong technical support for the smooth completion of the project, and have important guiding significance for the design and construction of similar projects.
