摘要
丁坝是整治海岸侵蚀的主要结构物之一。如何在特定的水动力条件和泥沙条件下建设具有岸线防护功能的丁坝,对整治海岸侵蚀具有重大意义。用数值方法研究丁坝建设后近岸的波浪、水流及泥沙运动,从近坝泥沙输沙率及近坝水流的变化分析探讨丁坝长度与角度的选取,得出不同沙滩坡度、波高、波向下沿坝裂流情况和近坝泥沙运动情况,并给出丁坝长度与角度的选取建议。
This paper studies the nearshore wave,current and sediment movement after building a groin by the numerical simulation, discusses the selection of the groin length and its angle based on the analysis of the changes of the nearshore sediment transport rate and the nearshore current,and obtains the along-groin rip current and near-groin sediment movement with different slopes of beach, different wave heights and different wave directions,with suggestions on the selection of the length and angle of the groin recommended.
