摘　　要：大型多连通域浮式平台的典型代表是大型海上旅游浮式综合体,依据概念设计,开展大型多连通域浮式平台的波浪载荷水池模型试验研究,试验对不同海况下4种典型多连通域浮式平台方案进行波浪载荷测量,包括剖面的垂向弯矩、水平弯矩和扭矩等,通过观察试验现象和分析测量数据,获得了不同方案大型多连通域浮式平台的波浪载荷特性。试验结果表明:由于平台质量大、振动阻尼大,所以高频载荷成分小;平台在自由状态下载荷值基本都小于平台只释放垂荡状态载荷值;在方案四高波高状态下,平台波浪载荷的高频成分包含了波浪的非线性、约束柱与平台之间的耦合、平台自身的高频振动等。研究成果可为大型海上旅游浮式综合体的结构设计提供设计载荷输入,支撑平台的强度校核评估。The large multi-connected floating platform(LMCFP),a typical representative,is primarily used for large-scale marine tourism floating complexes.The wave loads model test research of LMCFP is conducted in a basin,measuring wave loads under four typical multi LMCFP schemes under varying sea conditions.The measurements include the vertical bending moment,horizontal bending moment,and torque of the section loads.The wave loads characteristics of LMCFP with different schemes are obtained through the observation of the test phenomenon and analysis of the measured data.The high-frequency load component of the platform is small due to its large mass and vibration damping.The load values downloaded by the platform in a free state are generally smaller than those released by the platform in a heave state.The high-frequency component of the platform wave load includes the nonlinearity of waves,the coupling between the constraint column and the platform,and the high-frequency vibration of the platform itself in scheme four.The research results can provide design load input for the structural design of large offshore tourism floating complexes,and support the strength verification and evaluation of the platform.
