摘要

用纯数值模型代替了传统的水槽防波堤物理模型测试方法。在数值水槽中产生布雷施耐德/光康谱波,防波堤设计参照《中国海港水文规范》(以下简称《规范》)。求解了包含波反射项的修正Boussinesq型波动方程。通过与规范的比较,得出数值模型可用于防波堤的预设计,安全系数可用于规范。

Numerical Simulation of Nonliner Wave Propagating in Flume
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 numerical flume, and the design of breakwater is in accordance with Code of Hydrology for Sea Harbour, China ("the Code"). Modified Boussinesq type wave equations were solved including a wave reflection term. By purely simulation method, we have a reflection coefficient of 0.45, and in comparison with the Code, it is concluded numerical models can be used in the pre-design of a breakwater, and safety coefficient is used in the Code.
