中文摘要：
两流交汇是自然界最普遍的流动现象，汇流区的流态和水沙运动规律复杂，对市政规划、河道变化、生态环境等都具有重要的影响。本文以哈尔滨市三家子河段整治为例，采用二维k-ε模型研究了汇流区的流态，提出了优化堤线方案。计算结果表明：优化方案对防洪水位的影响很小，水流流态没有明显的改变，且堤线顺应河势、排漂导流合理，有利于工程区的景观和生态环境。研究成果对类似的工程具有参考价值。
英文摘要：
Stream confluences are one of the most common flow phenomena in nature. In the mixing zone, the flow pattern and the sediment moving laws, which have significant impacts on municipal planning fiver changes and ecological environment etc. , are even more complicated. Based on the fiver regulation work of Sanjiazi in Haerbing, the flow pattern of two streams confluences by 2D k - e model is studied in this paper. The calculation results show that the optimized plan has little influence on flood control and there＇s no obvious change in flow pattern. Besides, the bank line is well adjusted to the river regime, thus the floating debris discharge and river diversion become more rational. This is helpful to the landscape and ecological environment. The study results may be available for reference to similar projects.
