基于Aquifer Test的含水层水文地质参数计算——以塔城市供水改扩建工程为例

The hydrogeological parameter calculation of aquifer based on the Aquifer Test ——take the water supply reconstruction project of Tacheng city for example

水文地质参数的计算是水文地质勘察的一个重要环节。根据在塔城市北东方向喀拉墩地区进行的抽水试验资料,分别采用Aquifer Test软件和Dupuit公式迭代法计算抽水试验参数,对所求取的参数进行对比分析,通过Aquifer Test软件求取的参数与Dupuit公式迭代法求取的参数相近,各参数偏差率低,最终通过抽水试验数据,经不同的方法计算,确定含水层渗透系数K值为31.14 m/d。

The calculation of hydrogeological parameters is an important part of hydrogeological survey. According to the pumping test data in the Karadun area in the northeast direction of Tacheng City, the Aquifer Test software and the Dupuit formula iterative method were used to calculate the pumping test parameters, and the parameters were compared and analyzed. The parameters obtained by Aquifer Test software were used. It is similar to the parameters obtained by the Dupuit formula iterative method. The deviation rate of each parameter is low. Finally, the pumping test data is calculated by different methods to determine the K value of the aquifer permeability coefficient is 31.14 m/d.
