黄骅港潮汐推算及精度分析

Reckon on Tide and Its Precision Analysis at Huanghua Port

针对黄骅港验潮系统在工程应用中出现的数据缺测,研究了利用潮汐性质相似性判断指标和基于余水位配置的潮汐推算恢复缺测数据的可行性,分析了推算精度。结果表明,使用以上技术黄骅港缺测时刻水位数据的推算精度优于10 cm,可满足实际生产作业需要。

In order to solve the problem of fide data missing in the monitoring and issuing system about tide at Huanghua port, both indexs of judging comparability about tide kind and the technique of reckoning tide based on the collocation model of residual water level are researched . The numerical test results have shown that the reckoning error is in ± 10cm by the two techniques. It is significant to the work at Huanghua port.
