长距离引水工程中,合理选择输水系统的输水方式,对工程投资和运行管理有较大的影响。结合福建省平潭及闽江口水资源配置(一闸三线)工程中闽江竹岐~大樟溪引水工程输水系统输水方式的选择,分析有压隧洞输水及无压隧洞输水的优缺点;结果表明采用有压隧洞供水对于福建山区地形长距离引水工程中,在工程线路布置、运行管理及工程投资等方面均有一定的优势,可供类似工程借鉴。
In long-distance water diversion project, a reasonable choice of water delivery system of water delivery, the project investment and operation management have a greater impact. Based on the selection of the water delivery methods in the Zhuqi-Zhangzhangxi water diversion project of the Pingjiang and Minjiang River estuary in Fujian Province, the advantages and disadvantages of the water diversion in pressure tunnels and non-pressure tunnels are analyzed The results show that using pressure tunnel water supply has certain advantages for the project of long-distance water diversion in Fujian mountainous area in respect of project route layout, operation management and project investment, which can be used for similar projects.
