【摘要】：为了分析长江干流武汉至安庆河段建设"黄金水道"的可行性,采用资料分析、数学模型计算等手段,研究了长江上游溪洛渡、向家坝、三峡等11座水库联合运用后,该河段河道冲淤演变与航道条件变化趋势。研究成果表明,上游建库后,该河段总体河势仍将保持基本稳定,但局部河段可能会发生调整;上游建库对航道条件的影响总体上利大于弊,有利方面为枯水期的补水和航槽的冲刷,不利方面包括心滩和边滩冲刷可能引起的航槽不稳、碍航浅滩在蓄水期冲刷不充分、局部河段河势调整等变化。
[Abstract]:In order to analyze the feasibility of constructing "golden waterway" in the reach of Wuhan to Anqing along the Yangtze River, the combined use of 11 reservoirs such as Xiluodu, Xiangjiaba and three Gorges in the upper reaches of the Yangtze River has been studied by means of data analysis and mathematical model calculation. The evolution of scour and siltation and the changing trend of channel condition in this reach. The results show that after the upstream reservoir is built, the overall river regime of the reach will remain basically stable, but the local reach may be adjusted. The effects of upstream reservoir construction on channel conditions are generally more beneficial than disadvantages, and the favorable aspects are the replenishment of water during dry season and the scouring of channels. The disadvantages include the instability of channels caused by erosion of the heart beach and the beach, and the insufficient scouring of the shoals during the impounding period. Local river regime adjustment and other changes.
