摘　　要：根据大连及其附近海域11个站的波浪实测资料,研究分析了大连海域不同岸线段的波浪基本特征,包括常浪向、强浪向及其频率等,绘制了波浪玫瑰图;根据有关文献,对大连海域不同岸线外海深水波浪要素特征进行了分析研究,给出了50a一遇强浪向的波高和周期。结果表明:大连海域在渤海侧强浪向主要为偏北向,黄海侧海域的强浪向主要是偏南向。According to the wave data of 11 wave observation stations in Dalian sea area and nearby, the basic wave features of dominated wave directions, the strongest wave directions and their frequencies on different coastline segments are studied, and wave rose diagrams of 11 stations are drawn. Based on relevant literatures, the out-sea deepwater design wave characteristics on different coastline segments are analyzed, and the 50-year frequency wave heights and wave periods are presented. The results shows that the strongest wave direction in Dalian sea area in Bohai sea is of near-north, and that in Huanghai sea is of near-south.
