中文摘要:
      基于 Boussinesq 方程的 MIKE21-BW 模型,建立等水深、双突堤式的波浪数值港池,采用不同的波浪入射方向和双突堤口门宽度,分别对波浪经双突堤后的绕射情况进行模拟。根据 《港口与航道水文规范》 中的计算参数和突堤绕射系数结 果,对 BW 模型进行率定和验证,结果表明二者吻合度较好,可以较好地描述港池的泊稳状况。在此基础上,利用MIKE21-BW 模型对秦皇岛某港口防波堤工程的不同布局方案进行模拟计算和泊位稳定性分析,提出了工程设计方案建议。
英文摘要:
      A numerical wave basin, with the same water depth and double jetty, is established by MIKE21-BW model based on Boussinesq equations. And a numerical simulation of wave diffraction through double jetty is made using different incident wave direction and width of double jetty gap. The BW model is calibrated and verified based on the computational parameters and jetty忆s diffraction coefficient defined in Code of Hydrology for Sea Harbor. Results show a good agreement between the model output and theoretical calculation, suggesting that the model can simulate the berthing conditions of harbor well. On the basis of the above results, the harbor basin berthing of two different breakwater engineering projects in Qinhuangdao are analyzed, and some possible solutions are presented based on the simulated results.
