| 摘 要： | 桥墩周围局部冲刷深度是跨海大桥基础设计的重要参数。采用系列模型试验方法,对具体工程大型桥墩在水流和波流共同作用下的局部冲刷分别进行研究,提出了冲刷坑形态和最大冲刷深度,供工程设计参考。同时,通过单向水流和波浪 水流两种情况冲深结果比较,指出在预测波流共同作用下的大型桥墩局部冲深时,不应将两种动力条件进行简单的迭加,而应具体问题具体分析。 |
| 关 键 词： | 桥墩 波流 局部冲刷 |

| Abstract: | Local scour depth around bridge pier is a very important parameter in design of sea-crossing bridge base.In this paper,scale models are used to study local scour around bridge piers and abutments,and the scour pit pattern and maximum scour depth,which may serve as a reference for engineering design,are given.The results based on the experiments under steady current and under current-wave interaction show that it is necessary to analyze the dynamic conditions of wave and current in calculation of scour depth around practical bridge piers. |
| Keywords: | bridge pier wave-current local scour |
