摘　　要：为了探明南黄海辐射沙脊群波浪场特征,以指导这一海域的港口建设,采用波浪折射绕射数学模型模拟了该海域的波浪场.不同工况波浪场的模拟结果表明,该海域波浪传播具有如下特征:(a)等波高线环绕辐射沙脊群顶点港呈弧形分布;(b)波浪多次破碎;(c)不同方向入射波所形成的辐聚带,位置不尽相同;(d)入射波周期对波浪场影响显著.To study the wave characteristics of the radial sand ridges filed in the southern Yellow Sea and to guide the construction of harbors in this sea area,a mathematical model of wave refraction-diffraction was employed to simulate the wave transformation over the sea area. The simulated results of the wave fields under different situations were analyzed. A conclusion is drawn as follows： （a） the contours of wave heights distribute like an arc with Jianggang as its circle center; （b） the waves break for many times; （c） the locations of wave-energy-convergent zones generated by incident waves with different directions are different; （d） the period of incident waves has significant influence on the wave fields.
