摘　　要：本文介绍一艘无舱盖集装箱船在恶劣海况（相当于8级浪）中的甲板上浪压力试验结果，曾进行了预浪、艏斜浪、横浪、艉斜浪和随浪等七个浪向的试验。试验结果表明：甲板上浪压力最大发生在顶浪，最大压力值近4倍的船吃水水柱高，甲板上浪次数最频繁的浪向是艏斜浪，为26．5次／小时，横浪时上浪次数较少，而在艉斜浪和随浪状态则无甲板上浪。In this paper,model test results of pressure due to green water on the deck of a open top container ship in severial seas is presented. The model tests are carried out in seven wave headings: head waves (180°), head quarter waves (135°), beam wave (9O°), following quarter(6O°, 45°, 3O°) and following waves (0°) The test results indicated that the maximum pressure due to green water on the deek occurred in head seas (180°),and was approximately equal to 4 times the water-head of ship draft. Head quar ter to waves is the heading that green water occurred most freguently and was 26. 5 times/h,number of green water in beam waves was comparatively small, While during the test in following and following quarter waves,there was no green water at all.
