一、引 言 波浪的周期对海洋构筑物的波浪荷载有着强烈的影响.现今海洋构筑物设计所采用的、某一累积概率的波高和平均周期(或有效波周期)的设计波浪组合,往往不一定是对构筑物产生最大的波浪荷载.为此,各国常采用在既定的设计波高下,在可能发生的最大周期至最小周期的范围内,进行一系列的波浪荷载计算,以定出产生最大荷载的设计波浪周期.然而,初始的设计波浪组合是依据构筑物的设计标准,亦即是设计波浪的重视期而 I. INTRODUCTION The wave period has a strong influence on the wave load of marine structures.Wave combinations of wave height and average period (or effective period) of a certain cumulative probability used in marine structures design are often not always correct For this reason, a series of wave load calculations are often carried out in the range of the maximum cycle to the minimum cycle that may occur at a given design wave height, so as to determine the design wave generating the maximum load However, the initial design wave combination is based on the design criteria of the structure, ie, the emphasis period of the design wave
