Background
Hydrogeological parameters are important parameters for researching the flow problem of underground water, and finding out hydrogeological characteristics of an aquifer and determining seepage parameters by using a field pumping test method are one of important links and main means of hydrogeological exploration. The pumping test mainly determines the hydrogeological parameters of the aquifer: including permeability coefficient, water conductivity coefficient, water supply degree, elastic water release coefficient, pressure conductivity coefficient, permeability coefficient of the weakly permeable layer, cross-flow factor, influence radius and the like. And analyzing and determining the water-rich degree of the aquifer and evaluating the water outlet capacity of the well hole by measuring the water inflow amount of the well hole and the relation between the water inflow amount and the water level depth. At present, the defects of the pumping test in engineering investigation and hydrogeological investigation are mainly shown in the following three aspects:
