| 摘 要： | 介绍了北京大灰厂试验场（简称京西试验场）的概况，对１９９３年３月以来重力重复观测资料进行了处理。计算了各期重力观测精度，结果显示１９９３年３月～１９９５年５月京西试验场存在一定重力变化。采用给定的模型反演了八宝山断层介质的密度变化，认为断层破碎带介质密度的变化可能是引起地表重力变化的主要因素

| Abstract: | All of the gravity data measured in Dahuichang,Beijing(abb. Jingxi)testing field since Mar.,1993 are analyzed. Firstly, the precision of gravimetry of every cycle are calculated, then errors are analysed and disturbances are removed. It indicates that there were certain gravity changes from Mar.1993 to May.1995 in Jingxi testing field.The density of media of Babaoshan fault is obtained with the method of inversion under a given model.It is thought that the density change of media of shatter belt is perhaps the main factor causing the gravity change. |
