摘要
利用实测资料分析了象山港海湾对潮波的响应和湾内潮波变形．结果说明象山港对外海传入的半日潮波的振幅有明显的放大作用．M4和MS4两个浅水分潮在湾内快速增长造成了潮波变形和潮不对称性．潮波非线性的沿程变化和不同区域的潮能耗散说明湖滩与潮波变形关系不大，而湖波非线性在牛鼻水道中的增强对湾内潮波变形是重要的，1／4日分潮在湾内的共振作用也对M4和MS4两个浅水分潮起了放大作用．
The tide response and tide wave distortion are analyzed in Xiangshan Bay using a set of measurement data. The result shows that the semidiurnal tidal comPOnent propagated from open sea is amplified in the Xiangshan Bay. The tide and tidal currents are no long symmetrical, because of the M4 and MS4 comPOnent generation and their fast growthing. The tidal energy dissipation and tide and tidal current nonlinear coefficients along the main channel provide that the tidal flat has little contribution to the tide wave distortion, but the enhance of the tide wave nolinearty in Niubi Channel is important for the distortion. The effect of quarter-diurnal component co--oscillation amplifies the M4 and MS4 comPOnents in the bay.
