摘　　要：对于自升式钻井平台而言,风载荷在所有环境载荷中比重最大。现行规范在计算平台风载荷时主要采用面积投影法,不考虑各构件之间的空气动力学干扰的影响,导致计算结果偏于保守,不利于结构的优化设计。本文以CIMC自主研发的122m水深自升式钻井平台为例,对其于在位状态和迁航状态的风载荷进行风洞试验研究,并与规范计算结果进行对比验证。结果表明,试验结果要小于规范计算,空气动力学干扰和升力作用的影响不可忽略。Compared with other environment loads,the wind load takes up a much larger proportion in structure analysis for jack-up drilling platform.According to the MODU rules,the projected area method is used to calculate wind load.However,the aerodynamic interference between platform components is ignored,so the calculation results are conservative and not good for structure optimization designing.In this paper,a 400ft jack-up,which is developed by CIMC,is studied as an example.The wind loads in in-place and transit modes are obtained in the wind tunnel experiment.Compared with the results,which are calculated according to MODU rules,it indicates that the experiment results are less,and the effects of aerodynamic interference and lift can not be ignored.
