摘　　要：应用二维时域格林函数法对二维半定解问题进行了求解,应用发展的二维半理论和程序对WP60高速穿浪双体船在斜浪中的垂荡、纵摇、横摇和垂向加速度等运动响应及连接桥结构的波浪载荷进行预报,并把理论计算结果与模型试验结果及其它程序计算结果比较分析,初步验证了文中方法和程序在预报高速双体船运动及载荷性能中的适用性。The two dimensional transient free-surface Green＇s function was used to solve the formulation based on 2.5D potential theory.The motions such as heave,pitch, roll, vertical acceleration and cross structure wave loads of WP60 high-speed piercing catamaran were predicted by associated computer program. The results were compared with that calculated by SESAM, 2D theory and model test, and it indicates that 2.5D theory can predict the motions and wave loads of high-speed catamaran properly.
