【摘要】 本文根据作者以前提出的重力表面波线性和非线性相互作用理论解,系统地探讨波要素理论关系式工程应用计算方法,其中包括三维波、二维推进波、全反射及部分反射立波,以及斜向波与直墙相互作用,给出二种主要计算情况计算方法:迭代式(论证其收敛性)和级数近似解析式,并对计算结果作了分析比较,给出适用范围及计算精度。本文提出的计算公式比不久前Nielsen推荐的算式适用范围更广、精度更高。同时给出波动运动和动力因素过程解析计算方法以及综合考虑波浪折射、变形和水底摩阻损失的波高计算公式,便于编制相应的电算程序。更多还原

【Abstract】 On the basis of theoretical solution of linear and non-linear interactions among gravity surface waves, formerly presented by the author, computation methods in engineering for wave characteristics of long-crested, short-crested, full and partial reflected waves are discussed in detail. And the interaction of wave in oblique advance and vertical wall is studied as well. Iterative method with convergence shown and approximate explicit expressions are developed. Calculation results and practical proposals with error bounds presented here indicate that the expressions are more applicable and accurate than Neilsen’s. The analytical method for wave kinematic and dynamic processes is also given.更多还原
