| 摘 要： | 采用波数矢量无旋和波能守恒方程对圆形浅滩附近水域波浪绕射进行了数值计算，计算模型中采用Ｂａｔｔｊｅｓ关系与波数矢量无旋，波能量守恒方程一起联合求解圆形浅滩附近水域波浪折射影响下的波浪要素。本文的数值计算模型对圆形浅滩水域波浪折射绕射现象的验证结果表明，计算所得结果与试验结果是吻合的，数学模型是可靠和合理的，具有实用价值。

| Abstract: | In this paper, a numerical model is developed to describe the nearshore wave diffraction and refraction by using the irrotationality of the wave number vector and the wave energy conservative equation The Battjes relation is employed in the computing model to solve nearshore wave transformation of propagation wave The model is tested against laboratory measurements for the case of a submerged circular shoal on a slope, where both refraction and diffraction are equally significant The computing results show that the data of the computation and the test are well identical |
