摘要： 通过全面、系统分析双桥井“蠕变”水位异常与地震活动的对应关系,认为这类异常与地震活动的对应关系并不密切。从不同角度对这类异常可能产生的原因进行了分析,提出这类异常可能与井管的老化、腐蚀、破裂及由此引起的高矿化度的地表盐池水或浅层地下水的渗入有关。

Abstract: In this paper, a correspondence relationship between the“creep” anomalies of level of Shuangqiao well and seismic activity is comprehensively and systematically analysed, and it is considered that there is not close relation between the level anomalies and earthquakes. Possible causes leading to these anomalies are studied from various angles, and it is believed that they are related with that highly mineralized water seeps into the well from evaporating ponds of salt water above ground or shallow aquifer under ground, because of ageing, corroding and cracking of the well pipes.
