摘要
山西静乐井水位从2007年7月以来,出现了第4次高值异常,但此次异常的特征与以往高值异常存在明显的差异。文章根据影响静乐井水位动态变化的主要因素,从井区环境、同层地下水开采情况及降雨三方面对静乐井水位第4次高值异常成因进行了调查与分析,明确了此次异常的性质。同时,根据静乐井对地壳应力—应变的响应能力及高值异常与地震活动的对应关系,给出了其对未来地震趋势的预测意义。
Water level of Jingle well in Shanxi has presented 4th high value anomaly since July 2007, which is quite different in characteris- tic compared with previous ones. The causes to generate abnormal high value of Jingle water level are investigated and analyzed from aspects of the environment where well located, the extraction situation of same layer groundwater and rainfall. The nature of this abnormal high value is finally defined. Meanwhile, based on the response capability of Jingle well to the crustal stress-strain, and correspondence of its high value anomalies to seismic activity, the prediction significance for earthquake trend in the future is given.
