摘要
波浪在传播过程中,遇到建筑物和地形变化时,会发生绕射与折射,对波浪的传播、变形具有显著的影响。作者建立了基于Boussinesq方程的波浪数学模型。采用所建立的数学模型对双突堤条件下有、无航道时港内的波浪分布分别进行了数值计算,并将上述两种条件下的波浪分布情况进行了比较。结果表明,开挖航道对波浪的传播变形影响较大,不能用纯绕射来代替波浪的折、绕射联合作用。
Wave diffractions and refractions will occur when the waves meet structures and variational landform, which has remarkable influence on wave propagation. Based on the Boussincsq equation, a wave numerical model is developed. The wave distribution in harbor with breakwater gap is calculated and compared with and without navigation channels. The compared results show that the wave transmutation is greatly effected by the navigation channels and the refraction-diffraction model can＇t be replaced by diffraction condition only.
