目前,利用泰斯公式求水文地质参数常借助于配线法和雅克布直线法。但是,这两种方法都要求较长的抽水时间,尤其是直线图解法。除此之外,配线法还需要事先准备好标准曲线,没有标准曲线则不能计算。但本文提出的最大平均降速求参方法克服了上述缺点,不需用标准曲线,能使用较短时间的抽水资料求参,能使用任意u值,弥补了直线法不能使用大u值的缺陷。该方法并能充分利用全部观测资料,消除了偶然的测量误差,且计算简单,易于掌握。由于这些优 At present, the use of Teth’s formula for hydrogeological parameters often rely on the wiring method and Jacobs straight line method. However, both methods require longer pumping times, especially for straight-line diagrams. In addition, the wiring method also need to prepare a standard curve in advance, there is no standard curve can not be calculated. However, the maximum average speed reduction method proposed in this paper overcomes the above shortcomings, without using a standard curve, can use a shorter time of pumping data for reference, can use any u value, make up for the straight line method can not use a large u value defects . The method can make full use of all the observed data, eliminates the occasional measurement error, and is simple to calculate and easy to grasp. Because of these advantages
