摘　　要：为探究施工平台下表面在波浪场中可能受到的砰击荷载,文章通过几何比尺为150的物理模型开展了规则波对不同倾角和不同高度海上平台的砰击作用三维水池试验研究,讨论了入射波高、相对板长、平台相对高度与平台倾角与波浪砰击压强和砰击压力的关系。研究结果表明:规则波作用下波浪对平台的砰击压强及砰击压力具有随机性和周期性,高阶波浪砰击力明显;五个倾角平台受到的砰击压力随着相对板长的增大而减小;考虑波浪要素及结构倾角和平台净空高度等因素的影响,拟合出规则波作用下固定式海上施工平台下表面受到波浪砰击力的计算公式,可为规则波作用下的砰击力快速计算提供有益帮助。In this paper,the slamming force of the lower surface of the construction platform might be occurred in the wave field.The slamming effect of regular waves on offshore platforms with different parameters was studied through a serious of three-dimensional physical model tests with a scale of 150.The relationship between incident wave heights,relative plate lengths,platform heights and platform inclination angles and wave slamming pressure as well as slamming force were discussed.The results showed that the slamming pressure and slamming force of the wave on the platform under the action of regular wave are random and periodic,and higher-order wave slamming force was obviously observed.The slamming pressure of the five inclination platforms decreases with an increase in the relative plate length.Considering the influence of wave elements,structural inclination angles and platform clearance heights,the calculation formula of wave slamming force of fixed offshore construction platform under the action of regular waves was fitted,which can help to quickly calculate the slamming force on the construction platform in regular waves.
