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。
Through the on-site survey of the observation environment of Jiashi 55 Well, the inspection and calibration of water level and working status of water temperature meter, the experiment of temperature gradient of two wells, the measurement and macroscopic survey of 17 wells in 10 km range 7 water points of water quality and water dissolved gas analysis results, initially determine the Jiashi new wells 55 water level of a large, rapid increase in the anomaly of the observation shaft wall damage caused by infiltration of shallow water, do not belong to the earthquake precursory anomalies.
