摘　　要：本文采用数值模拟与理论分析相结合的手段,从圆端形桥墩周围行进水流的特征和变化进行研究分析。模型试验中采用环翼式防冲板对桥墩进行防护。通过Flow-3D流体力学软件进行数值模拟分析,得出圆端形桥墩周围行进水流及其流场变化情况;研究圆端形桥墩绕流流场特征和桥墩冲刷特点,探索圆端形桥墩绕流和冲刷之间的关系,以期为圆端形桥墩绕流及冲刷研究提供理论依据和新的研究思路。By means of numerical simulation and theoretical analysis,this paper studies the characteristics and changes of the water flow around the round pier.In the model test,the piers are protected by the ring-fender.Through the Flow-3 d fluid mechanics software for numerical simulation analysis,draw a rounded shape marching Flow and the change of the Flow field around piers;Study the flow field around piers rounded shape characteristics,and the characteristics of the bridge pier scour,explore the rounded shape the relationship between the flow around piers and scour,in order to rounded shape flow around pier scour study provides theoretical basis and new research way of thinking.
