| 摘 要： | 在利用重力测量结果研究地壳垂直运动时，重力－高程因子的确定是一个需要研究的问题。本文提出利用多期复测水准网与重力网动态联合平差的方法，同时求解地壳垂直运动速率和重力－高程因子。利用此方法对北京地区１９８３－１９９１年的水准和重力复测结果进行了计算，结果表明：两类不同观测值的权比配置是恰当的，平差模型是正确的、重力－高程因子的分布符合一般规律。

| Abstract: | When studying vertical crust deformation by use of data of gravity measurment,it is a problem to determine gravity-altitude factor.In this paper,the methud of dynamic combined adjustment for repotition network of levelins and gravity is presented.Using this method,the speed of vertical crust deformation and the gravity-altitude factor can be solved simultaneously.The data of the repetitonal leveling and gravity in Beijing area from 1983 to 1991 are coniputed by use of this method.The results show that the weight disposition of two kinds of observed values is suituble,the model of adjustment is right,and the distribution of the gravity-altitude factor conformis to the general law. |
