国家水准原点网重力异常影响

The Influence of Gravity Anomaly In National Leveling Origin Network

介绍了国家水准原点网的情况,概括了水准面不平行改正、空间重力异常、布格重力异常和重力异常改正的计算方法,并利用实测重力值和高程数据进行计算分析,发现该区域重力异常影响极其微小可忽略不计。

In this article the contents introduce the national leveling origin network, summarize the methods to calculate lev- el surface not parallel correction, spatial gravity anomaly, bouguer gravity anomaly and gravity anomaly correction, and value and elevation data is calculated using the measured gravity, found that the regional gravity anomaly is so small as to he ignored.
