摘要
为研究燕窝山工程海域在不同的防波堤平面布置下的波浪场分布特征,应用波作用守恒方程和Boussinesq方程建立了大、小范围的波浪数学模型对工程区附近海域的波浪场进行数值模拟,统计并分析工程前后防波堤附近波浪特征站位的波要素。基于防波堤基本布置方案1,改变防波堤的长度和轴线角度,根据不同平面布置下的防波堤对波浪的掩护效果进行比较分析。结果表明,综合考虑防波堤附近波浪场的变化特征、防波堤特征站位波要素的变化及防波堤的有效掩护面积3个方面,将防波堤轴线以两段堤相交处为圆心逆时针旋转8°,并将直堤向东侧延长100m,即方案2为优选方案。
In order to study the distribution characteristics of wave field under different layouts of breakwaters in the engineering sea area of Yanwoshan,we carry out a numerical simulation of wave field near engineering area by using wave action conservation equation and Boussinesq equation to establish wave mathematical models in large and small scale,and analyze the wave parameters of wave observation station near breakwater.We change length and axis angle of breakwater based on the first plan so as to compare the shielding effect of waves under different layouts of breakwaters.The results show that when variation characteristics of wave field,wave parameters of wave observation station and effective shielding area are overall considered,the second plan is the suitable choice,the axis of the breakwater is intersected at the intersection of two dikes,the center is rotated 8°counterclockwise,and the embankment is extended 100 m to the east side.
