摘要/Abstract

摘要： 位于南京城市上游的长江新济州汊道段的整治工程正在实施。由于新济州汊道段河道历来多变,近10多年来对于该汊道段的整治方案一直存在争议,其焦点主要在于其整治方案中中汊封堵工程对河道稳定的影响。河道河相关系是表征河道稳定特性的重要参数,借助于该河段平面二维水沙数学模型计算成果,从整治方案实施前后的河相关系变化出发,进行河段整治稳定分析,从而对中汊封堵方案的合理性进行研究。研究结果表明:采用封堵中汊整治方案,新生洲左汊河道泥沙更容易产生落淤,对新生洲右汊河道稳定影响不大。

Abstract: Along with the development of Nanjing city, the regulation project of Xinjizhou reach, which is located in the upstream of Nanjing, is under implementation. But the regulation program has been controversial over the last decade because this branch of the Yangtze River is changeable. The focus of controversy mainly lies in the effect of blocking the middle branch on the river’s stability. Since hydrogeometric relation is an important parameter reflecting the stability of river reach, we analysed the hydrogeometric relation before and after the implementation of the regulation project based on the result of 2D mathematical water-sediment model research. Result suggests that if the regulation program of blocking the middle branch is adopted, the left branch of Xijizhou reach is prone to deposition, but no big influence is shown for the right branch.

Key words: Xinjizhou reach of the Yangtze river, river regulation, hydrogeometric relation, stability of river reach, mathematical water-sediment model
