摘要
通过分析裘家洲、扬子洲和焦矶头近年的演变趋势,阐明赣江尾闾分汊河段实施洲头控导工程的必要性,并建立平面二维的水流泥沙数学模型。对比分析了工程实施前后该河段的流场、岸线演变、河床冲淤和分流比变化情况。得出洲头控导工程能有效的导顺水流,保护岸线,减缓河床冲淤和稳定分流比。
It is necessity to construct deltaic control project at the lower reaches of Ganjiang River where water current divides by analyzing the evolution trend of QiuJiazhou delta, Yangzizhou delta and Jiaojitou delta in recent years. A 2-D mathematical model of flow and sediment is established to compare and analyze the variation of flow field, shore evolution, river bed siltation ＆ scouring and split-flow ratio before and after the construction. By the end, it is concluded that deltaic control project can effectively guide water current, protect the shoreline, reduce the siltation and scouring on river bed, and stabilize the split-flow ratio.
