摘要
在现有地震流体研究成果基础上，借地下水位的时空异常图象进行推测区域构造断裂活动的探索。通过对天津地区１９８５至１９９４年地下水位异常的分析对本区构造活动给出了以下推测：①１９８９年大同６．１级地震对地区构造活动显示出突出的调整性的变化。②沧东断裂带是本地区最活跃居主导活动地位的断裂。③沧东断裂带应力集中部位有由天津西南段向东北转移的迹象。
Based on the achievements in seismological fluid research,we analysed the time and space patterns of groundwater level anomalies in the period of 1985-1994 in Tianjin area,the main results are as follows:(1) The 1989 Datong earthquake with Ms6.1 shows a adjusting change of regional tectonic activitIes ;(2) The Cangdong fractured zone is still a main active fractured zone in Tianjin area ;(3) It is found that the stress concentration position in Cangdong fractured Zone showed a kind of transfered trace from the southwestern section to the northeastern section.
