摘要
长江下游安庆水道中汊发展影响到河势及左汊主航道条件的稳定,为此实施了航道整治工程以对安庆中汊进行控制。依据工程前后多年的实测水文、地形资料,并采用河工模型试验研究手段,分析中汊形成及快速发展的原因,并对支汊控制方案进行试验研究,进而提出推荐方案。工程实施以来的效果分析表明,采用护底工程进行支汊控制可以起到有效控制汊道分流、改善航道条件的目的。
The development of the middle branch of Anqing waterway in the downstream of the Yangtze River has a great influence on the river regime and the stability of its left branch.Therefore, waterway regulation projectwas implemented to control the middle branch.Analyzing the causes of the middle branch ＇s formation and rapid development according to the observed hydrologic data during the project, and carrying out experimental study on the branch control scheme, we put forward the recommended scheme.The engineering effect analysis of the projectindicates that by controlling the branch with the bottom protection structures , we can improve channel conditions.
