南水北调跨安阳河倒虹吸工程对河道的影响

南水北调中线工程总干渠沿程需修建多座跨河建筑物,这些建筑物穿越河道时,会造成河道河势变化,可能带来不利的影响。通过物理模型、数学模型等技术手段,分析研究工程对河势的影响是十分必要的,针对南水北调中线跨安阳河倒虹吸工程,研究了工程实施后对安阳河河势、冲淤变化等方面带来的影响,提出倒虹吸工程的优化设计方案。

The Influence on Stream Channels of the Inverted Siphon Project Across the Anyang River in the South Water-to-North Project

Along the trunk canal of the mid-section of the south water-to-north project many bridges have to be built.The bridges running across the river may bring about the changes of the river regime,which will cause unfavorable results.It is very necessary to analyze and study the effects of the project on the river regime through technical methods,such as physical model experiment and mathematical model experiment.This article studies the effects caused by the construction of the inverted siphon project across the Anyang River at the mid-section of the south water-to-north project,and bring forward the best construction plan of the project.
