| Abstract: | The study object in this paper is the Quaternary deep-aquifers in the central North China Plain.We obtained reliable data of non-steady flow from two fixed flux pumping tests at a 525-m deep well.Two observation ways,manual observation and automatic DIVER,were used to observe the dynamic change of groundwater level from the pumping well before and during the groundwater pumping and during the drawup of groundwater level.After analyzing the hydrological and geological conditions of the aquifers and the pumping test data,the data of drawup of groundwater level are selected to calculate the hydrogeologic parameters.On the basis of improving the general simplified arithmetic,tp value and its effect are obtained to calculate the parameters,and then a simpler and more credible method,Cooper-Jacob arithmetic,is regarded as the optimal method to calculate the hydrological and geological parameters of the aquifers.In improving the calculation method,when tp was the duration of non-steady flow,the calculated and observed T values are 186 m2/d and 134 m2/d respectively.Compared with the classical method,such results are very different.Calculated with Cooper-Jacob method,the T values of two non-steady flow pumping tests were 255 m2/d and 231 m2/d respectively,which were close to the results calculated with the classical method. |
