摘要
通过确定不同重现期的风速极值,阐述建立风生海流推算关系及风生海流的特点,给出渤海湾海区风因子的合理取值范围,并描述海流极值的计算方法和计算过程,以解决近岸海区海流极值的计算问题。结合唐山LNG终端站码头区工程海流现场调查及当地历年连续风速数据,确定不同重现期风速极值及风生海流极值,并给出海流极值的结果。该工程采用重现期法进行风生海流计算及海流分析,对于海洋功能开发、灾害预防、港口建设及各种建筑设计具有重要作用。
The characteristics and the calculation of the wind-driven current were expounded via the computing of the wind speed extreme value in the different return periods, and a reasonable value range of the wind factor in the Bohai Bay was given, and the method and the process of the calculation of the current extreme value were also describes in it for resolving the question on the calculation of the current extreme value in the offshore. Combining with the current field investigations and the local continuous wind data of the past years in Tangshan LNG terminal landing, the extreme value of the wind and the wind-driven current in the different return periods are worked out, and the results of current extreme current in the return period is applied in the analysis of the value are output. The calculation of the wind-driven current in the Tangshan LNG terminal landing, which will play an important role in the function development of the sea; disaster prevention; harbor construction and all kinds of architecture designing.
