- 摘要:
- 聊城地震水化站水温观测井于2008年8月出现奇异变化，水温大幅度指数型下降。作者在收集分析井区水文地质背景条件的基础上，调查研究了奇异变化的可靠性、产生的原因及作为地震前兆异常的可能性。结果表明，奇异变化可能是井管老化微裂，导致新的低温含水层中地下水渗入井内而引起的，作为地震前兆异常的可能性很小。
The observation well of water temperature in Liaocheng SeismHydrochemistry Station has appeared strange change since August 2008. The water temperature showed exponential drop. In this paper, the dependability of the change, reason for appeared and possibility for portent of earthquake were investigated and researched based on collection and analysis on the background condition of hydrogeology and geology in well area. The result indicated that the strange change may be induced by infiltration of groundwater of other aquiclude. The infiltration may be induced by aging and tiny crack of well tubes. Then the hypothesis that the strange change is novel portent of earthquake is questionably.
