中文摘要：

为研究船舶甲板上浪冲击压力的特点和规律，针对ITTC国际标准船模S-175进行了水池试验．模型试验采用自航模方式，同步测量了波浪参数、船舶运动、上浪高度、上浪冲击压力等时间历程数据．采用高频率、大量程压力传感器通过改变浪高、浪向、航速、船舶艏部外飘来分析这些因素对船舶甲板上浪的影响．试验结果表明：增大船舶艏部外飘对减缓船舶甲板上浪的作用不是非常显著，在较高海情下还会加剧上浪；试验在国际上首次测到翻卷砰击上浪压力，数据显示翻卷状波浪直接冲击甲板所产生的瞬时砰击压力对甲板的破坏性远远大于波浪涌上甲板，应得到更多重视．

英文摘要：

In order to study the characteristics and law of green water impact pressure of ship, a water tank experi- ment was carried out for the ITYC international standard containership model S-175. In the model test, the self-pro- pulsion ship model was utilized. The wave elevation, ship motions, wave height of green water, the impact pressure on the deck were synchronously measured during the model test. During the experiment, the green water phenome- non was analyzed by using the measured data through parameter variation of a series of factors including incident wave height, wave headings, ship speed and the how shapes. It was shown by model testing that the effectiveness was limited in reducing the impact loads from deck green water by increasing the flare of the ship＇s bow. On the contrary, the phenomena of green water could get intensified in a high sea state. In the model test, the impact pres- sure from rolling waves of green water was the slamming pressure by the direct impact the impact loads induced by the deck swell study. observed internationally for the first time. The measured data shows that of rolling waves on deck is far seriously destructive, in comparison with of green water. The impact of rolling waves on the deck requires further
