利用GPS水准对模拟大地水准面进行约束，采用“移去——恢复”技术和多面函数法进行拟合内插，得到转换后的大地水准面。
The GPS-levelling is used to add constraints on the simulated geoid, and the "remove-restore" method and the multi-quadric function method are used to interpolation, so as to obtain the refined geoid.
承包商应按工程师可能随时发出的指示，移去工程的任何部分的覆盖物，或在其内或贯穿其中开孔，并应将该部分恢复原状使之完好。
