【摘要】 介绍了在波浪与建筑物相互作用的物理模型试验中的两种新的波浪分离方法:基于Hilbert变换的解析方法及插值方法。应用该两种方法可以精确地估计入射波和反射波的幅值以及反射系数等参数,能够获得入射波和反射波之间的相位信息,可以很好地应用在波浪分离中。将由该两种方法得到的反射系数与传统的Goda的方法进行了比较,证明上述两种方法的可靠性,并通过数值模拟和物理模型实验证实了所得的结果与实际值吻合得非常好。更多还原

【Abstract】 Two new methods are presented in this paper to separate composite waves: analytical method using Hilbert transform and interpolation method.The amplitudes and reflection coefficients of the incident and reflected waves as well as the phases of the incident and reflected waves can be estimated by the present methods.Numerical sample tests and physical model experiments are also conducted to prove the accuracy of the two methods,and the results of the two methods are compared with Goda’s method.更多还原
