| 摘 要： | 进港航道开挖引起波能重新分布 ,导致航道外近区域波能聚集 ,波高增大 ,从而影响防波堤稳定及港内泊稳条件。文章介绍了 Boussinesq方程的推导过程和发展过程 ,基于深水和缓变地形的色散关系 ,建立了波浪数学模型。该模型可用于研究深水和浅水地区波浪的浅水变形、折射、绕射和反射。并提出了减少波能聚集、降低堤前波高的多种措施。结合大窑湾港实际工程 ,经过多方面的数物模比选 ,利用数学模型优化出一种可行的喇叭口航道开挖方案并付诸实施 ,降低了防波堤的堤前波高 ,满足了预期的设计要求。

| Abstract: | The redistribution of wave energy caused by channel excavation results in the convergence of wave energy and increasing wave height in the zone nearby channel, and thereby influences the stability of the breakwater and the condition of berth in harbor. The paper introduces the process of the deduction and development of Boussinesq equations, and establishes the mathematical model of wave based on improved dispersion characteristics that suit deepwater and lowly-varying bottom. The model has high accuracy and can be used to study wave deformation, refraction, diffraction and reflection in deep water and shallow water. In this paper, some measures are presented to decrease the convergence of wave energy and reduce the increasing wave height in front of the breakwater. Combined with the practical project of Dayaowan Harbor, and compared the result of mathematical model with physical model, the proposal of digging bell-mouthed channel is optimized and brought into effect. This reduces the increasing wave height in front of the breakwater and makes the demand of predicted design. |
