摘　　要：为考察码头面板尾部开缝和面板上开孔2项措施对减小波浪对斜坡接岸式高桩码头上部结构冲击的效果,在波浪水槽中进行了相应的规则波模型试验.通过分析试验数据研究了开缝和开孔对面板上波浪上托力冲击特性、压强分布、上托力大小的影响.试验结果表明,面板尾部开缝对冲击压的大小和位置有一定影响,对冲击压的影响和开缝宽度有较大关系.开缝对总上托力的影响有限.开孔后总上托力变小,并且开孔数越多,总上托力减小得越多.但板上开孔对减小冲击压的效果不是很明显.In order to investigate the effect of two measures, setting gap in the rear part of wharf deck and opening holes in wharf deck, on reducing wave impact on the superstructure of a shore-connecting high-pile jetty on a slope, regular wave tests were conducted in a wave flume. The influences of setting gap and opening holes on the impact characteristics, the pressure distribution and the magnitude of wave uplift forces were studied based on the analysis of collected test data. The test results show that setting gap in the rear part of wharf deck influences the magnitude and position of impact pressure. The influence on the impact pressure relates significantly to the gap width, while there is limited influence on the total uplift forces. The total uplift forces decrease with the opening of holes in decks. As the number of holes increases, the total uplift forces decrease in magnitude. However, opening holes in wharf deck has little effect on reductions of the impact pressure.
