摘　　要：目前,船级社规范中没有针对海洋平台砰击载荷的计算方法,一般采用船舶砰击载荷的计算方法,但其计算结果偏差较大。基于波浪能量守恒原理,定义波浪能达到的最大等效高度,利用势流理论开展海洋平台的运动响应计算和长期预报,提出一种波浪砰击载荷等效计算方法。将试验测试结果与采用船级社规范公式计算得到的结果进行对比,验证了所提方法的准确性。Currently,there is no method for calculating the slamming load of offshore platforms in classification society rule,the calculation method of ship slamming load in the rule is generally adopted,but the deviation of the calculation result is quite large.Based on the principle of conservation of energy of wave,the maximum equivalent height H that the wave can reach is defined,the potential theory is used to calculate the motion response of offshore platform and forecast in the long run,an equivalent calculation method of slamming load is proposed.By comparing the experimental test result and the formula calculation result of the classification society rule,the accuracy of the method in the paper is verified.
