黄、渤海近海海浪环境测量与分析

利用近海海浪环境开展大尺度船模试验是一种有效的船舶性能试验技术,了解近海海浪环境特征对该试验的开展具有重要意义。文中对黄、渤海多个海域近海海浪进行实地测量,采用谱分析法得到测量海浪的有义波高、特征周期、波能谱等参数,并将实测波浪谱与大洋谱进行无因次化比较,讨论了实测波浪谱与大洋谱的相似性。分析结果表明特定风向与潮汐条件下近海海浪谱与大洋谱具有相似性。

Ocean wave measurement and analysis along the Yellow Sea and Bohai Sea

Taking advantage of offshore wave environment to carry out large-scale ship model test is an effective testing technology for ship performance.The characteristics of offshore waves should be adequately researched when the large-scale ship model tests are conducted,which is a key factor to success.In this paper the offshore waves in several area along the Yellow Sea and Bohai Sea are measured and the method of spectral analysis is adopted to calculate the significant wave height,period,wave spectrum and some other parameters.The measured wave spectrum and the ocean spectrum are handled into dimensionless form to evaluate their similarity.The results show that the offshore wave spectrum is similar to the ocean spectrum under specific conditions.
