摘　　要：用半解析方法研究孤立的截断的浮式Spar平台主体的一阶绕射问题,在入射波浪周期为4～40s的范围内分别得到迎浪0(°)和45(°)角时的纵荡激励力、垂荡激励力和纵摇激励力矩图,得到的数值计算结果与MOSES和WAMIT应用软件计算结果一致。所得计算结果,可应用于Spar平台的运动计算。The spar hull is simplified as an isolated truncated vertical floating circular cylinder. A semi-analytical method is described to solve the first order diffraction problem for the Spar platform. When the period of the incident wave varies between 4 and 40 seconds and the wave heading is zero degree and 45 degrees, the surge wave excitation force, heave wave excitation force and pitch wave excitation moment are obtained respectively. Comparisons between the numerical results given here and those obtained from MOSES and WAMIT show excellent agreement. The results can be used in the calculation of Spar platform motion.
