摘要
对2009年以来的重力资料采用新的8位点号平差程序,利用绝对重力控制的相对重力测量10期资料进行了经典平差计算和系统误差检验分析,揭示了经系统误差改正后的重力变化结果较小,基本符合山东正常重力变化幅度。另外,对测网的传递误差带来的影响进行了简单的讨论,从而基本去除无震异常值较大的弊端,为合理科学分析山东重力场变化特点提供了前提条件。
Calculating gravity data since 2009 with new eight digit adjustment program, this paper analyzed typical adjustment and system error using ten volumes relative gravity data. The gravity results after system error erection basically accorded with gravity change in Shandong. They also discussed influence for survey net caused by transmission error which solved large anomaly without earthquake problem and provided premise for gravity research in Shandong.
