摘　　要：本文给出具有不同反射系数(Ro变R_γ)楔形堤或隅角堤波浪绕射一般解析解,其中包括R_0=R_γ和R_0=-R_γ两种情况作为特例。推导出适用于工程应用计算的相应数学模型及计算方法。同时提供单突堤、直线堤及各种隅角堤等情况的计算结果及比较。In this paper a general analytical solution is presented for wave diffraction by a wedge or corner of arbitrary angle yn (0<γ≤2)with different reflection coefficien-ts(R0 and Rγ), in which the cases of R0 =RγandRγ = -R0are included as special ones. The corresponding mathematical models for computations in engineering applica tioas are derived.Numerical results and comparisons of some important special cases, such as semi-infinite breakwater (γ=2) , infinite straightline wall ( γ = 1 ) ,andcorners of angle γπ=2π/3,π/2,π/3,π/4 are given.
