本文提出了利用s-t、s-lgt和lgs～Igt三种曲线确定水文地质参数的切线法。利用该方法求参数不需要准备标准曲线和特殊的函数值表,可利用短期抽水资料确定参数,适于抽水现场整理资料。
This paper presents a tangential method to determine the hydrogeological parameters using three curves of s-t, s-lgt and lgs ~ Igt. It is not necessary to prepare the standard curve and the special function value table for the parameters by this method. Parameters can be determined by the short-term pumping data, and it is suitable for the on-site finishing of pumping data.
