楠溪江供水工程设计综述

楠溪江供水工程是浙江省水资源配置的大型长距离供水工程,由拦河闸取水枢纽、输水线路等建筑物组成。工程设计很好地解决了在风景区河道、感潮河道末端复杂地质条件下拦河闸的布置、基础处理、洄游鱼道等技术问题。输水系统采用运行管理方便、节能的有压重力输水方式。工程经过多年运行实践,设计技术成熟可靠,运行管理方便。本文系统介绍了工程设计的方案比选及关键设计技术问题,可为类似工程设计提供参考。

Review on design of Nanxijiang River Water Supply Project

Nanxijiang River Water Supply Project is an important water resources allocation project in Zhejiang Province，which is a large scale long-distance water supply project consisting of the structures of river barrage with water intake works，water conveyance route，etc. The engineering design better solves the technical problems，such as river barrage layout，foundation treatment，fish migration way，etc. under the complicated geological condition of the channel in scenic region and the end of tidal river. For the water conveyance system，the mode of pressure-gravity water conveyance is adopted，which is energy conservative and convenient for operation and management. Through the operation for several years，it is demonstrated that the design technique is mature and reliable，while the operation management is convenient as well. The scheme comparison and the technical problems from the key designs during the design of the project are systematically described herein，so as to provide some references for the similar engineering design concerned.
