Aquifer Test Method for Calculating Hydrogeological Parameters of Leaky Confined Aquifer

为了准确评价越流承压含水层地下水资源量,探寻一种简便精确计算水文地质参数方法成为关键性问题。利用清丰县八里庄水源地勘探项目非稳定流越流承压含水层抽水试验资料,采用Aquifer Test软件,根据越流承压含水层非稳定井流理论,计算承压含水层的水文地质参数,并对其计算结果与采用数值模拟方法所得结果进行比较分析。结果表明:Aquifer Test软件对水文地质参数的计算简便快捷,计算结果符合水文地质实际情况,是合理选择越流承压含水层水文地质参数较为精确的方法。

In order to accurately evaluate the amount of groundwater resources in confined overflow aquifers,it is a key issue to explore a simple and accurate method for calculating hydrogeological parameters.Based on the pumping test data of unsteady flow over-flow confined aquifer in Balizhuang water source exploration project of Qingfeng County,this paper used Aquifer Test software to calculate the hydrogeological parameters of confined aquifer according to the unsteady well flow theory of over-flow confined aquifer,and the calculation results were compared and analyzed by numerical simulation method.The results show that the calculation of hydrogeological parameters by Aquifer Test software is simple and fast,and the calculation results are in line with the actual situation of hydrogeology,which provides a more accurate calculation method for the reasonable selection of hydrogeological parameters of overflow confined aquifer.
