本文对非稳定流抽水试验参数计算，通过一定的变量代换和数值转换．提出了一种解析法的改进方法。该方法除能快速算出含水层水文地质参数如导水系数、弹性释水系数和渗透系数外．还综合考虑了各种假定和约束条件；并对所求出的水文地质参数是否满足当地水文地质条件进行判断．改进和完善了原有的解析计算方法，从而为准确计算含水层水文地质参数提供了一种有效途径。 In this paper, unsteady flow pumping test parameters are calculated, through a certain number of variable substitution and numerical conversion. An improved method of analytic method is proposed. This method can not only quickly calculate the hydrogeological parameters of aquifer such as the conductivity coefficient, elastic release coefficient and permeability coefficient. But also comprehensively considered various assumptions and constraints; and judged whether the obtained hydrogeological parameters meet the local hydrogeological conditions. Improve and perfect the original analytical calculation method, and thus provide an effective way to accurately calculate the hydrogeological parameters of aquifers.
