摘　　要：针对船舶高速航行、离靠码头倒车、舰艇摇摆幅度较大等情况下测深仪可能会出现明显测深度不准的情况,论文对基于潮汐计算的水深获取方法进行研究。分析了如何已知高低潮潮高潮时求任意时刻潮高潮时,已知主港求副港潮汐,并通过验潮站及主副港影响范围求任意地潮高潮时。通过潮汐值的计算,可作为测量水深的一种备用手段,并对测深仪水深信息的准确性进行检验。In view of the situation that the depth sounder may have obvious inaccurate measurement when the ship is sailing at high speed,astern from the dock,and the ship has a large swing amplitude,this paper studies the water depth acquisition method based on tidal calculation.How to find the tide height and tide time at any time when the tide height and tide time of high and low tide are known is analyzed.The arbitrary height and time of the earth tide can be obtained through the influence area of the tide measuring station and the main and auxiliary ports.The calculation of tidal value can be used as a backup means to measure the water depth,and the accuracy of the water depth information of the sounder can be checked.
