| 摘 要： | 对九江地震台大气降雨、浅层抽水和深层含水层应力释放对区域应变场影响的分析表明,九江台应变观测对局部应力应变场有较强的敏感性,有可能捕捉到强震的区域应力应变场变化过程,但目前要区分非地震因素和地震前兆孕育过程的影响还较为困难.

| Abstract: | This paper discusses influence on the local stain field data from the three factors:rainfall,shallow pumping,deep level aquifer stress releasing at Jiujiang seismic station,and analyzes the dynamics machanisms of them.The results show that the local stain observation at the seismic station is sensitive to the local stress-stain field,and it may catch the information of the local stress-stain field changing progress caused by the strong earthquake.However it is very difficult to distinguish the non-earthquake factors and earthquake precursor inoculation progress. |
