| Abstract: | Based on the theoretical analysis about height anomalies in the vevr-bay surveying area of the Hangzhouwan Great Bridge, a height fitting method using the transitional curved surface is presented in this paper. A surveying project of the GPS geodetic height is made, in order that the precision of the GPS geodetic height in the sea satisfies the need of vertical control of pier platforms. These results are references for application of the GPS vertical surveying in sea-crossing projects. |
