排水倒虹吸是南水北调中线工程左岸排水建筑物中数量最多的一种型式。鉴于总干渠沿线复杂的地形地质条件和水力学条件,每座排水倒虹吸的工程布置都有其自身的特点。本文以南水北调中线一期工程总干渠鲁山北段李村沟排水倒虹吸的工程布置为例,浅析其工程布置的基本思路,为以后优化排水倒虹吸的工程布置提供参考。
Siphon inverted siphon is the type of the largest number of drainage structures on the left bank of the Middle Route of the South-to-North Water Diversion Project. In view of the complex topographic and geological conditions and hydraulic conditions along the main canal, each drainage siphon project has its own characteristics. This paper takes the arrangement of Licungou Diversion Siphon in the north Lushan section of the main canal of the first stage of the South-to-North Water Diversion Project as an example to analyze the basic idea of the layout of the project and provide reference for the future optimization of the engineering layout of inverted siphon drainage.
