一、前言波高和周期是波浪的两个基本要素,工程上常以工作海域相应的波高和周期为其特征,选择一种“设计波”来计算波浪力。设计波是一种极端波浪。如“50年”或“100年”一遇的波浪,应用这种单一波高和周期的规则波来近似地分析不规则波的作用并对海工建筑物进行设计是方便的。人们通常选用某一概率的波要素作为设计值的方法(称为特征波设计法)。随着波谱理论的研究发展,按海浪谱的组成考虑不规则波的设计也日趋广泛。对于直墙建筑物而言,在波谱作用下波浪力对建筑物的动力反应只需考虑海浪谱中代表波的作用。而对于
I. Foreword Wave height and period are two basic elements of wave. In engineering, the wave height and period corresponding to the working sea area are often used as their characteristics, and a “design wave” is selected to calculate the wave force. Design waves are extreme waves. Such as the “50 years” or “100 years” once the waves, the application of this single wave height and period of regular waves to approximate the role of irregular waves and offshore structures designed to facilitate. People often choose to use a certain probability of wave elements as the design method (called eigenvalue design method). With the development of spectrum theory, the design of irregular wave according to the composition of the wave spectrum is also increasingly widespread. For straight-walled buildings, the dynamic response of wave forces to buildings under the action of the spectrum only needs to consider the role of waves in the wave spectrum. And for
