摘　　要：在沿海港口工程采用的《海港水文规范》(JTS145—2—2013)中,并未就常见的混合浪给出波浪周期的计算公式,以致实际工程设计中混合浪周期的选取比较困难。本研究基于小振幅波理论,利用能量法推导二维混合浪周期的计算公式,可供工程设计参考。Current Standard on Hydrology of Seaport （JTS145--2--2013） being applied to coastal harbor engineering has not yet provided a formula for the calculation of the period of compound wave which is frequently encountered in engineering practice. Thus it is very difficult to determine the value of compound wave period in engineering design. Based on small amplitude wave theory, energy method is adopted to deduce the formula for calculating the period of 2D compound wave, which will provide references for engineering design.
