摘要
本文利用数值计算和经验公式相结合的方法,获得了在波浪和风生流和波浪共同作用下海底泥沙输移的二维模型.在此基础上,讨论了海底泥沙输移在风速、风向和泥沙粒径不同等三种情况下的变化特征;指出了经验公式对泥沙输移规律的适用范围以及风速、风向对于近岸处泥沙输移重要性.这一研究结果对近岸结构物的选址设计具有实际应用价值.
By using the method of combined numerical computation and experiential equations, the two dimensional model which describe the sediment transport caused by both wind and wave on the seabed is got in the paper, after that, the features of sediment transport with different wind speed ,wind orientation and the sediment＇s diameter are discussed, we point out the proper cases in which the experiential equations could be used, and also the importance of wind speed and wind orientation of sediment transport, which is useful in the design of structures near shore.
