摘要
通过对伽师新55井观测环境的现场勘查,水位及水温仪工作状态的检查与标定,2个井水温度梯度的实验,周围10 km范围内17个水井水位的测量和宏观考察,并结合7个水点水质和水中溶解气的分析结果,初步判定此次伽师新55井水位大幅度、快速上升异常现象为该观测井井壁破损渗入浅层水所致,不属于地震前兆异常。
Based on the spot investigation of observation environment for new No.55 well,writers inspected and calibrated the working state of thermograph,and then made the experiment on water temperature gradient of two wells.At the same time,writers did measurement and microscopical investigation on water level of 17 wells at a range of 10 km.Combining with the analysis results of water quality and dissolved gas for 7 water points,writers judged that the abnormal phenomenon of high and rapid rising for new No.55 well was caused by shallow formation water infiltration as the crack of observation shaft sidewall,which did not belong to precursor anomaly of earthquakes.
