摘　　要：本文结合海图基本测量实例,总结了水位数据预处理、基准面确定、水位精度评估等实施步骤及技术细节。余水位同步变化曲线与精度评估结果能直观、严谨地确定余水位强相关验潮站。经严密论证,在大亚湾海域应用基于余水位监控与潮汐模型的水位改正法,能满足水深测量精度,符合相关规范要求,可替代传统水位改正方法,优化验潮站布设方案,减少验潮站数量。Coupled with the basic measurement examples of sea charts, the implementation steps and technical details of water level data preprocessing, datum surface determination, and water level accuracy evaluation are summarized in this paper. The residual water level synchronization curve and the accuracy evaluation result can directly and rigorously determin the residual water level strong correlation tide station. After careful argumentation, the water level correction method based on the residual water level monitoring and tidal model can be applied in the water of Daya Bay to meet the accuracy of water depth measurement and meet the requirements of relevant specifications. It can replace traditional water level correction methods, optimize the layout of tide gauge stations, and reduce the amount of tide stations.
