近年来研究地下水动力学有许多新方法,数理方法就是其中之一。兹简介如下: 含水层参数的确定首先必须确定含水层的蓄水系数和透水系数。将抽水试验所测得之水位降深值和水量代入适当方程式,便能得出上述参数。观测数据的整理抽水试验成果的分析,可用迭加原理法进行。其原理就是:抽水时任一点的地下水位降深值等于各井对该点水位削减值的总和。透水系数T和蓄水系数S按下式计算:
In recent years, there are many new methods to study groundwater dynamics. Mathematical methods are one of them. Here is a brief introduction: Determination of aquifer parameters First of all, it is necessary to determine the aquifer’s water storage coefficient and water permeability coefficient. The above parameters can be derived by substituting the water level drop and the water amount measured by the pumping test into the appropriate equation. Analysis of the data collected Pumping test results can be superposed principle method. The principle is that any point below the groundwater table at pumping depth equals the sum of the water cut values at each well. Water permeability coefficient T and water storage coefficient S are calculated as follows:
