摘　　要：合理选择穿越方案是长距离引水工程成功实施的关键。西江引水工程设计中根据各障碍物的不同特点,在做了大量细致的工作后,综合考虑地形地质条件、障碍物的功能与特性、障碍物管理单位的想法、工程占地、工程安全及工程投资等多种因素,对不同障碍物选择了开挖埋管、沉管、跨越、盾构等等不同方案。各方案都得到主管部门的认可,工程实施时各障碍物穿越施工都很顺利,从而保证了整个工程的顺利实施。The selection for Pipeline construction methods is crucial for long- haul water supply engineering. In this case this paper offers an example for selecting pipeline laying method under different circumstances. The author outlines the major engineering characteristics of pipeline construction methods applied in the West River Municipal water supply project. It includes trenched piping method,underwater installation, pipeline bridge, shield machine tunneling, etc, according to the geotechnical conditions and peculiar terrain,as well as the client's consideration, engineering area, safety and cost- efficiency. With the refined technique and careful designing,the project acquires all necessary licenses and implements smoothly.
