摘要：

本文介绍了用拉柯斯特-隆贝格G型重力仪进行的南极长城站((?)=62°12′.9S,(?)=58°57′.8W)重力基准点国际联测和南极菲尔德斯地区重力及形变监测网建设和观测情况.测得长城站重力基准点重力值及精度为:982208.682±0.021mgal.极地重力网由18个重力点组成,其控制面积近40平方公里,用闭合环式方法观测.网的平均测段精度为±0.029mgal,并对不同运输情况下的观测结果进行了精度分析.

Abstract:

In this paper the international connection measurement of gravity datum points at Antarctic Great Wall station ( p= 62°12.19s, λ=58°57.18w) by using Lacoste - Romberg gravimeters G and the network layout of gravity and deformation monitoring stations in Fielders region of Antarctics and its observation are presented. Values of gravity datum points and accuracy obtained at Great Wall Station are 982208.682 and ±0.021 mgal respectively. The gravity network of polar area is composed of 18 gravity points. Its control area is about 40 square kilometers. Average measuring section accuracy of the network is ±0.029 mgal. Accuracy analysis for observation results under the condition of different transportation is carried out.
