中国黄骅港基准面的计算与分析

CaIculation and Analysis of Datum at Huanghua Port of China

针对黄骅港航道二期工程对潮汐运动的影响,计算了航道三个位置的基准面,研究了黄骅港新的潮汐规律,据此建立了航道各位置深度基准面的精化数学模型,作为该模型的工程应用,设计了黄骅港的航道基准面;最后检验了系统的潮汐预报精度。

In order to studied the change of tide rule duing to the second channel engineering at huanghua port, tidal observation precision was evaluated about tide monitoring and issuing system at huanghua port. Mean sea level and depth datum were calculated and new tide rule was researched. On the basis, a critically mathematical model of datum is proposed in the paper. Channel datum about different place of channel was designed for engineering application. The numerical test results have shown that the calculation, the design and the engineering application of datum at huanghua port has important signification and application value to engineering and production, and so on.
