| 摘要: |
| [目的]研究港内波高分布特征及有限风区内风作用对波高的影响。[方法]以某码头工程为例,结合MIKE 21 BW波浪模块及小区风成浪计算公式对港内波高进行计算,并对计算结果进行分析。[结果]计算组合中,W向、WSW向风作用下,港池西侧斜边岸线及西侧岸线前沿水域受岸线遮蔽的影响,波高相对较低,而湾底及东侧岸线前沿受外海入射波影响较大,波高相对较大。风作用对港内波高有一定的影响,W向风作用下,风浪对湾底岸线及东侧岸线前沿各观测点波高的贡献分别为9%~15%及12%~15%,WSW向风作用下分别为13%~35%及16%~41%。[结论]风作用对有限风区内波高的影响不容忽视。 |

| Abstract: |
| [Objective] In order to study the effect of wind forcing on the wave height distribution in limited wind zone.[Methods] We took a port project as an example. The wave height distribution was calculated using the MIKE 21 BW module and small wave wind wave calculation formula.[Results] The result shows that when the wind direction is W or WSW,the wave height at the west side of the port is relatively low because the shoreline blocks the wind. The wave heights at the bottom and east side of the port are relatively large. The wind has some influence on the wave height of the port. The W wind wave is about 9%~15% and 12%~15% of the total height at the rear and east side. The WSW wind wave is about 13%~35%and 16%~41% of the total height at the rear and east side.[Conclusion] The effect wind forcing on the wave height of port is significant in limited wind zone. |
