摘　　要：弯道环流、涡旋等不良流态往往是天然游泳场的安全的不利因素,不良流态的形成与河道的天然条件、人为活动两方面因素相关。文章在分析闽江西河河段河势、流态的基础上,建立该河段的二维数学模型,针对不同的自然条件和整治方案,对该河段的水动力特性进行研究,在此基础上,提出整治效果较优的河道整治方案。在天然河道游泳场整治过程中,除了考虑到对游泳场局部流场流态的优化调整之外,还要综合考虑整治工程对河道通航、行洪的其他功能影响,进行综合比选。Adverse flow conditions such as circulation flow and vortex are often considered as the disadvantageous factors affecting the safety of the natural bathing beach,and the formation of adverse flow relates to both the natural channel condition and human activities. In this paper,the hydrodynamic characteristics of the river and the optimized channel regulation scheme were studied by setting up a two-dimensional mathematical model that based on the analysis of Minjiang River morphology and flow condition. Research results indicate that in the process of natatorium river regulation,in addition to considering the local flow field of natatorium flow optimization adjustment,other functions of the channel such as navigation,flood discharge must be considered in order to make a comprehensive comparison.
