| 摘 要： | 传统的以物理模型进行的防波堤断面实验被以计算机进行的数字波浪槽代替,边界造波为Bretschneider/Mit-suyasu波浪谱,防波堤断面根据海港水文规范(简称“规范”)设计。以改进的Boussinesq波浪方程,通过引入波浪反射项以数值模拟实现了波浪在水槽中传播的全过程。通过数值水槽获得了波浪在本文防波堤断面前0.45的反射系数,将数值模拟的结果和规范中的反射系数进行了对比得出,数字波浪水槽有满意的精度以及在规范中使用了一定的安全系数,表明数字波浪槽在防波堤的预设计中有重要作用。 |

| Abstract: | The convention method of testing breakwaters in flume by physical model was replaced by purely numerical model.A Bretschneider/Mitsuyasu spectrum wave was generated in a numerical flume,and the design of breakwater was in accordance with Code of Hydrology for Sea Harbour,China("the Code").Improved Boussinesq type wave equations were solved including a wave reflection term.By purely simulation method,reflection coefficient of 0.45 was obtained,and in comparison with the Code,it is concluded that numerical models can be used in the pre-design of a breakwater,and safety coefficient is used in the Code. |
| Keywords: | breakwater pre-design numerical flume Boussinesq wave the Code |
