| 摘 要： | 依托实际工程,应用数值模拟的方法分析圆形和矩形沉井在不同流速、流向等条件下桥墩周围流场分布情况,并与物理模型试验结果进行对比。结果表明,数值计算结果与物理试验结果吻合良好;交角不同,局部冲刷坑的外形轮廓也发生相应的变化。

| Abstract: | Based on practical engineering,the flow field distribution of circular caisson and rectangular caisson under different velocity and flow direction are analyzed by numerical simulation method.At the same time,it contrasts the calculation result of numerical simulation and physical model test.The results show that: the result of numerical simulation and physical model test is in good agreement;if the intersection angles are different,the contour of local scour hole also changes correspondingly. |
