实测重力异常与布格重力异常在高精度水准测量改正中的精度比较

按照一等水准测量要求在水准测点上进行重力测量。在水准测量数据处理中进行相同的水准标尺改正、正常水准面不平行改正、水准标尺尺长改正等，但在重力异常改正中采用实测重力异常和布格异常两种方法进行重力异常改正。比较两种方法对水准点高程改正的影响，并进行精度分析。

Precision Analysis of the Measured Gravity Anomaly and Bouguer Gravity Anomaly in the Correction of High-Precision Leveling

Gravity measurements are performed by adopting the technical requirementsof first-class level measurement. For leveling data analysis and calculation during the course of processing, we deal with the same level staff correction, not parallel of the normal level correct, the feet long correct of leveling staff, and so on. In the process of the gravity anomaly correction, this paper uses the observed gravity anomaly correction and Bouguer anomaly correction for gravity anomaly correction in two different ways. Finally, we compare the results of the leveling point elevation correction and analyze the precision of the two methods.
