摘　　要：为充分利用历史数据并减少测量区域验潮仪抛设的投入,且不降低测深精度,技术人员通常应用同步验潮历史数据并采用天文潮位加余水位的方式推算海中原定点潮位。文章对技术要求中的概念进行了详细解释,同时基于曲线比较传递法利用同步验潮历史数据对定点验潮进行水位推算,并对推算的精度进行验证和探讨,最后得出结论。In order to make full use of historical data and reduce the investment of tide gauge in the surveying area,without reducing the surveying accuracy,the technicians calculate the fixed-point tide level in the sea by using the historical data of synchronous tide measurement and adopting the method of astronomical tide level plus residual water level.The concepts in technical requirements are explained in detail,and this paper uses the historical data of synchronous tide measurement to calculate the water level of the fixed-point tide gauge based on curve comparison transmission method.The accuracy of the calculation is verified and discussed,and finally the conclusion is drawn.
