摘要
采用平面二维数学模型,在理想矩形水槽中对不同夹角下桥墩组对流场的影响及桥墩优化布置进行了研究,并通过工程实例计算进行了进一步印证,结果表明:将左右幅桥墩错开布置可较好地减少因桥墩组中轴线与水流方向夹角过大而引起的对河流流场造成的不利影响。
Using the plane 2-D mathematical model, this paper carried out the research for the affection of the piers group with different angles to the flow direction and piers group optimal layout in an ideal rectangular flume, then verified the results of the study by the practical project. The results make cheat that stagger layout of the left pier and the right pier can reduce the affection to the direction of the flow by the big angle with the piers group.
