摘　　要：基于分离规则合成波的解析方法,提出了不规则合成波分离的理论技术,将不规则波浪等价为特定频率规则波进行分离,首先通过数值模拟方法检验,分离叠加30%噪声的模拟合成波浪,分离精度利用相关系数评价达0.97,然后测试无反射造波水槽中的现场合成波浪,经波谱分析,分离精度能够达到工程标准。The paper proposes a theoretic method to separate the composite irregular waves into incident and reflected waves, based on the analytical method （AM）. Irregular waves are decomposed into regular components. Firstly, the result of separation of the irregular waves, which adds 30% of noises by numerical simulation, is evaluated by coefficient correlation. Then the real composite waves in the non-rereflected wave-making flume are considered. Analysis of wave spectrum shows that the precision of separation is high, and satisfy the needs.
