本文对剑川、禄劝和石屏地震前后所进行的流动重力测量作了分析研究。结果表明:在±20—±25微伽精度范围内,震中距测线6—60公里的情况下,剑川、禄劝地震前后均未出现明显的重力异常变化。石屏地震前近东西走向的扬武—石屏测线剖面有一些趋势性重力变化。
This paper analyzes the gravity flow measured before and after Jianchuan, Luquan and Shibing earthquakes. The results show that there is no obvious gravity anomaly change before and after the Jianchuan and Luquan earthquakes in the range of ± 20- ± 25 microgatres with epicentral distance of 6-60 km. Near the east-west front of the Shibing earthquake, the Yangwu-Shijie line profile has some trendy gravity changes.
