Abstract:Pumping test is an important means to determine hydrogeological parameters.Pumping test includes stable flow pumping and unstable flow pumping.In unstable flow pumping test,the Type curve method is widely used to solve hydrogeological parameters in engineering practice.However,the analysis and calculation of the original data of unstable flow pumping test is a very cumbersome process,which requires solving a large number of formulas,and the results often vary from person to person.The use of manual curve-fitting method and Excel to obtain hydrogeological parameters is also subject to subjective factors.In response to the characteristic that the standard curve of the Type curve method is basically consistent with the measured curve shape,the corresponding sum of squared deviations function is obtained using the least squares method.The Nelder-Mead algorithm is used to find the minimum value of the sum of squared deviations to achieve the optimal fitting of the translated measured data to the standard curve,thereby reducing manual errors.
