摘要
依据秦皇岛海洋站34年实测资料统计分析出的不同重现期的波浪要素,针对某拟建修造船厂工程总平面布置方案,利用TK-2D波浪数学模型及MIKE21的BW方程波浪数学模型,对工程建成前后的波浪场进行模拟。确定了工程区域各等深线处的设计波要素,论证了船厂码头和不同的防波堤、进港航道平面方案布置对港内的泊稳条件、拟建码头前的波浪变形情况以及波浪变化对码头作业天数的影响。模型中考虑了波浪的折射、绕射、反射、底部损耗等因素,为工程设计提供依据。
According to the 34-year site wave data from Qinhuangdao Ocean Observation Station,we obtained the design wave conditions of the variable return periods.TK-2d wave model and MIKE21 BW wave model were used to simulate the wave transformation near a dockyard.The design wave conditions along the contours near the engineering were obtained from the models.The wave height diagram in the harbor,the wave height near the dock and the wave＇s influence on the working days of the dock were discussed between different breakwaters,channels and dock arrangements.In present model,the wave diffraction,wave refraction,wave reflection and bottom friction were taken into consideration for a better dockyard design.
