摘　　要：弯道取水口附近水域水流结构十分复杂,为研究其水力学特性,依据物理模型试验,分析弯道及取水口附近表层速度场分布,采用标准模型对其进行二维数值模拟。综合分析可知,取水口处流速变化剧烈,应特别注意工程维护;取水口下游流速明显降低,应采取适当措施防止泥沙淤积。According to the physical model,3D ultrasonic current-meter is utilized in this paper to measure three-dimensional flow structure directly under different conditions near water intake.Numerical simulation of the two dimension flow has been simulated by using standard turbulent model.Comprehesive analysis,the velocity at the water intake change rapidly.The velocity at the downsteam of water intake significantly reduced.
