摘　　要：针对目前利用非稳定流抽水试验资料求解水文地质参数所存在的问题,通过对泰斯非稳定流计算公式中井函数的优化拟合,建立了一个二元线性回归方程,利用求解回归方程中的待定常数反求含水层的水文地质参数的新方法,与传统的其它计算方法比较,本文方法具有计算简捷,不依赖图表,求解精度高等优点。Aiming at the present issues of calculating hydrogelogical parameter based on some data of the unsteady flow pumping water test, through the optimized imitation of well function of the Theis unsteady flowing calculated formula, the paper establishes the regression equation of duality linearity, using the waited constant of the formula to counter - calculate the hydrogeological parameter of the aquifer, compare to the traditional other method, the method has some strongpoints of simple, not depending the chart and high precision.
