同井不同埋深地温探头的地震前兆观测效应

Earthquake Precursory Observatory Effects of Geo-Temperature Sensors Mounted at Different Depth in the Same Well

一、前言 2001年,在首都圈工程数字化台网改造过程中新建了一批地温观测台站,还有相当一部分台站在老的地温观测井孔里重新放置一个新的地温探头,新老探头同时观测。在清理和研究地温观测资料时,我们发现在同一井孔中,不同埋深的地温探头,所记录到的温度变化曲线形态是不相同的。另外,不同地方井孔的水温潮汐反映形态也不相同。在此,我们对这一现象进行初步分析与研究。

The geo-temperature precursory anomaly and co-seismic effect have been recorded and analyzed in present paper.The water-temperature tidal wave effect observed at different depth of the same well is also studied.It is important for us to further study its mechanism for a better forecast.
