| 摘 要： | 针对目前利用水位恢复期的降深资料求解水文地质参数所存在的问题,以泰斯非稳定流计算公式为基础,通过对井函数的优化拟合,建立了一个一元线性回归方程,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,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。

| Abstract: | In order to solve the problems existed in the process to get the solution of hydrogeological parameters by using the drawdown date during groundwater level recovery,a simple linear regression equation on the basis of Thesis unsteady flow formula and the optimal fitting of well function is set up which makes use of the undetermined constants in the regression equation to solve the hydrogeological parameters of the aquifer. Compared with the traditional calculation methods,the said method bears the advantages such as simple calculation,non-dependence for charts and higher precision of solution. |
