摘要
本文以收集现有全国各省地震局流动重力测量资料和图件为主，结合大区域联测资料，用绝对重力点控制联网并进行统一平差。平差程序采用经典相关间接平差方法，以压缩存贮方式解算法方程。计算结果表明：全国重力网段差平均精度为０．０１０７×１０－５ｍｓ－２。辽宁地区点值精度最高为０．０１９×１０－５ｍｓ－２，一般为０．０２０×１０－５－０．０３０×１０－５ｍｓ－２。
In the paper, absulute gravity points are used to control on network and conduct a method of unified adjustment based upon collecting the existing data and diagrams of mobile gravity measurements from different provineial bureaus throughout the county in connect with link information by the great regions. In the adjustment procedure it adopted a adjustment method of traditional correcate indirect adjustment, to take normal equation by means of concentrated storage. The caluclation results showed that the average accuracy of difference in the national gravity network is 0. 0107×10-5ms-2. The maximum accuracy of point value in Liaoning area is 0. 019×10-5ms-2, generally it is 0. 020-0. 030×10-5ms-2.
