摘　　要：对散货船、油船、集装箱船的多艘实船进行了短期波浪载荷直接计算,分析了这三种船型的船舯垂向弯矩、L/4(L为船长)处垂向剪力、3L/4处垂向剪力的若干规律,以及集装箱船型的扭矩、船舯水平弯矩的若干规律。根据这些规律,总结出一套针对特定船型的短期波浪载荷极值的完整计算公式。Direct calculations of the short-term wave induced loads are carried out for the actual ships of bulk carder, oil tank and container ship. The laws of the vertical mid-ship bending moment, the vertical shear fore at L/4 （L is ship length） and the vertical shear force at 3L/4 are analyzed for the all three types of ships, and the torque and horizontal mid-ship bending moment for the container carder. According to these laws, a set of simple formula for the extreme value of short-term wave induced load are given in this paper.
