单孔抽水试验称作井试验,有别于设置有观测孔的含水层试验。井试验无专门水位观测孔,且受井的完善程度、施工工艺及井结构等因素的影响。井中水位下降值失去真实性,其Q=f(s)则为上述诸因素的综合反映。所得资料用常规方法计算的含水层水文地质参数亦受其影响而降低可靠程度。但单孔抽 A single hole pumping test is called a well test, as opposed to an aquifer test with an observation hole. There is no special observation hole for well test, and it is affected by factors such as well completion, construction technology and well structure. Well water level loss value loss of authenticity, its Q = f (s) is a comprehensive reflection of the above factors. The obtained data are also affected by the conventional methods to calculate the hydrogeological parameters of aquifers and reduce their reliability. But single-hole pumping
