海上临时验潮站深度基准面计算与分析

Calculation and Analysis on Depth Datum Plane of Temporary Sea Tide Station

为提高海上临时验潮站深度基准面推算精度,根据上海长江口2个临时验潮站的实测数据,采用3种不同的深度基准面推算方法进行基面的计算和比较分析,认为最小二乘潮位拟合传递的方法具有较高的精度,建议推广使用。

To improve the calculation accuracy of the depth datum plane of the temporary tide gauge station, with the measured data of two temporary tide stations in the Yangtze River Estuary in Shanghai, the depth datum plane is analyzed and calculated by three different methods. The method using the least square fitting transfer method to calculate the depth datum plane is of high precision and is recommended to be used widely.
