| 摘 要： | 全面分析重力测量的各种误差和目前能达到的精度后，对垂直形变监测中引入重力观测值的可行性进行了具体研究。结果表明，若仅是为了测定点的垂直位移的高程速率，增加重力测量数据后对形变分析的精度增益十分有限。但是对于大跨度垂直形变监测和局部地区突发性垂直形变测定，重力测量方法可以及时掌握垂直形变的趋势

| Abstract: | The investigation of the feasibilities associated with the use of gravity observation in vertical deformation analyses has been conducted through the com plete estimates of error effects and obtainable accuracies in gravity observations.Itturns out that the accuracy increase is quite limited by using gravity observation to analyse vertical deformation,if the aim is only to determine point vertical displacement and its velocity.However the trend of vertical deformation can be detected in time with the help of gravimetry to monitor large scale vertical deformation or local drastic ones. |

| Keywords: | monitoring of vertical deformation gravity gradient velocity of vertical displacement |
