南水北调中线工程作为南水北调工程的一部分,对缓解河南、河北、北京及天津地区日益突出的水资源供需矛盾具有重要意义。中线一期工程总干渠将与许多河流相交,跨河道工程布置成为总干渠建设过程中的重要问题。本文介绍了中线一期工程总干渠跨越午峪河的倒虹吸工程的设计和布置方案,为其它倒虹吸工程的设计和布置提供了有益的参考。
As a part of the South-North Water Diversion Project, the mid-route of the South-to-North Water Diversion Project is of great significance for alleviating the increasingly prominent contradiction between supply and demand of water resources in Henan, Hebei, Beijing and Tianjin. The main trunk of the first phase of the midline will intersect with many rivers, and the arrangement of trans-river works will become an important issue in the construction of the main trunk. This paper introduces the design and arrangement of the inverted siphon project of the main trunk of the midline first phase across the Wuyu River, which provides a useful reference for the design and layout of other inverted siphon projects.
