摘　　要：波浪对透空式海上建筑物的冲击作用已经成为影响此类建筑物安全的重要因素.进行了单向规则波对方形水平板冲击作用水槽试验研究.总计进行了4个方向(0°,垂向规则波;15°、30°、45°,斜向规则波),入射波高H=7.5～20.0cm,增量2.5cm,周期T=1.0～2.0s,增量0.2s,水平板底面距离静水面的高度Δh与H的比值0～0.5,增量0.1的试验研究.采用小波分析方法去除了由于测压传感器振荡引起的测量数据的噪音信号.讨论了上托力与相对入射波高H/d、相对板宽B/L、相对净空Δh/H的关系.The impact of wave on open marine buildings is of significance for safety of these buildings. The test wave is unidirectional and regular wave. The experiments are carried out with perpendicular regular waves （β=0°） and oblique regular waves （β= 15°,30°,45°）, the wave heights H ranging from 7.5 cm to 20.0 cm with 2.5 cm increment, the wave periods T ranging from 1.0 s to 2.0 s with 0. 2 s increment, and the clearance of the model with respect to the wave height Ah/H ranging from 0 to 0. 5 with 0. 1 increment. Wave impact pressures are obtained by using wavelet analysis to remove noise signals from the dynamic responses of the instruments. The influence of different incident wave parameters, including the relative incident wave height H/d, the relative plate width B/L and the relative clearance Ah/H on the wave uplift forces, is discussed.
