摘要
2012年8月栾城王家庄井水位短时间内多次出现快速、大幅下降变化,调研发现,下降异常由距离该井约860 m的新井抽水引起。利用抽水试验模型,定量模拟抽水对王家庄井水位的变化影响,模拟结果与实际变化量相当,进一步确定该井水位下降异常为抽水影响。
The water level of Wangjiazhuang well in Luancheng rapidly and sharply declined within a short time for many times in August 2012.Through the investigation,we considered that the anomaly is caused by pumping on the well distance of about 860 m from Wangjiazhuang well.Through pumping test model to quantitatively simulate pumping effect on Wangjiazhuang well water level change,the result shows that simulation results is close to the actual change,to further confirm declining anomaly of the well water level is caused by pumping effect.
