根据钻孔抽水试验资料,计算岩石渗透系数,是水文地质工作的重要项目之一,但该项工作相当耗费时间,且易出差错,尤其在野外无计算设备(如计算机)的情况下,直接将已知的一系列数值代入公式进行计算,更显得繁重,而所得结果不够准确,甚至错误。本文主要目的在不违反数学原则,以裘布依基本公式为例,进行简化与变换,再根据经验数值结合实际情况编制换算表,尽量利用查表,避免复杂的算术运算,从而提高渗透系数计算速度及其正确性;凡以裘布依基本公式导出的其它公式(抽水、注水、单孔、
According to the drilling pumping test data, calculating the rock permeability coefficient is one of the important projects in hydrogeological work. However, this work is quite time-consuming and error-prone. Especially in the field without computing equipment (such as computer), direct Putting a series of known numerical values into the formula to calculate is even more heavy, and the result is not accurate or even wrong. The main purpose of this paper is not violating the principle of mathematics, with Qiu Buyi basic formula as an example, to simplify and transform, and then based on empirical data with the actual situation of the preparation of the conversion table, try to use the look-up table to avoid complex arithmetic operations, thereby increasing the permeability coefficient calculation speed And its correctness; Where Qiu Buyi according to the basic formula of other formulas (pumping, water injection, single hole,
