摘　　要：采用仿泰斯公式,探讨了潜水非稳定流完整辐射井抽水试验水文地质参数的求解方法,建立了水文地质参数反演优化模型;为了进一步简化优化模型的求解过程和提高计算精度,通过优化拟合的方法,提出了泰斯井函数的拟合函数式;将求解反演优化模型转化为求解一元线性回归方程中的系数,利用回归方程中系数反求含水层的水文地质参数,通过实例验证了该方法具有可行性与合理性。Using the imitation Theis formula, the methods of solving hydro-geological parameters in phreatic aquifer were discussed on the complete penetration of radial well unsteady flow pumping test, and the hydro-geological parameter inversion optimization model was established. In order to simplify the solving process of the optimization model and improve the calculation precision, the formula of the Theis well function was put forward by optimizing fitting method. The hydro-geological parameters in the phreatic aquifer were obtained by solving the coefficients of regression equation, and the established method was reasonable and feasible through a pumping instance.
