摘要
塘沽水厂107井系唐山大震中反映明显的井孔。1975年开始观测,1986年7月以来,该井水质成分变化大,异常增多。为此,作者进行了系统的抽水试验和现场调查,对水质变化原因进行了分析。对于107井异常的剖析,为当前抽水水化观测井干忧因素的排除,异常机理的探讨提供了很好的依据。
The precursory anomalies of hydrochemical constituents at No. 107well of Tanggu waterworks in Tianjin are rather apparent in the Tangshan earthquake. But since July 1986, the ionic concentrations .in large magnitude have been detected in the well. In order to study the variational cause of the ionic components, the pumping test and the field investigaion were performed. The results obtained are helpful to explain water quality anomalies, to eliminate the interference factors for other pumping well and to understand the anomalous mechanism.
