潮位推算技术在盘锦长航道水深测量中的应用

Application of tide level calculation technology in bathymetry of long Panjin Channel

针对盘锦长航道水深测量中的潮位控制问题,通过对潮汐理论进行研究,根据盘锦航道具体情况,采用基于潮汐调和分析的潮位推算技术,建立潮位推算模型,对海上长距离航道进行潮位控制。通过海上定点实测潮位、推算潮位数据比对及不同时间段航道沿线水下地形测量数据比对得出,2种方法得到的数据资料均满足相关规范要求,充分表明基于潮汐调和分析的潮位推算技术准确可靠,能够满足水深测量精度需要,可以在同类型的长航道水深测量中应用。

Regarding the issue of tide level control in the bathymetry of the long Panjin Channel, this paper studies the tidal theory and builds a tide level calculation model by a tide level calculation technology based on tidal harmonic analysis according to the specific situation of the Panjin Channel to control the tide level of the long distance offshore channel. By comparing the measured data on the tide level at fixed points at sea with the calculated tide level data and the measured data on the underwater topography along the channel in different time periods, the paper finds that the data obtained by the two methods all meet the requirements of the relevant specifications. The results fully testify to the point that the tide level calculation technology based on tidal harmonic analysis is accurate and reliable, can meet the accuracy needs of bathymetry, and can thus be used in the bathymetry of long channels of the same type.
