长江八卦洲汊道水沙特性与治理

Water and sand characteristics and regulation of Baguazhou branch of Yangtze River

结合汊道水沙特性,在对长江八卦洲汊道现有整治工程分析的基础上,采用数学模型进行汊道整治工程数值模拟,并对不同整治方案及整治效果进行了研究.结果表明,八卦洲汊道采用洲头鱼嘴向上游延伸整治工程,是有效实现汊道分流稳定的整治措施.

Based on analysis of the existing regulation of the Baguazhou branch of the Yangtze River and its water and sand characteristics,mathematical models were employed to numerically simulate the regulation projects. Various regulation plans and their effectiveness were studied. The results show that the regulation of the Baguazhou branch and extension of the bar head upstream can effectively stabilize the discharge.
