为了测试Diver自动水位记录仪在抽水试验求参中的应用效果,在北京房山琉璃河地区进行了抽水试验,比较了Diver与测绳获取的抽水试验原始数据特点,利用Diver数据计算了水文地质参数。整个抽水试验全过程,Diver监测与人工实测的主孔数据平均差值为0.17m,副孔平均差值0.02m。据Diver数据,最终确定该区域的水文地质参数:渗透系数k为91.51m/d、导水系数T为1555.72m2/d、储水系数S为0.0314。Diver自动水位记录仪具有数据连续、数据量大和准确性高等优势,从数据来源上确保了求参结果的合理性。
In order to test the application effect of Diver automatic water level recorder in pumping test, the pumping test was conducted in Liulihe, Fangshan, Beijing. The characteristics of raw data of pumping test obtained by Diver and measuring rope were compared. The hydrogeological parameters . The entire pumping test the whole process, Diver monitoring and manual measurement of the main hole data average difference of 0.17m, deputy hole average difference of 0.02m. According to Diver data, the final hydrogeological parameters of the region: permeability coefficient k is 91.51m / d, water conductivity coefficient T is 1555.72m2 / d, water storage coefficient S is 0.0314. Diver automatic water level recorder has the advantages of continuous data, large data volume and high accuracy, and ensures the reasonableness of seeking results from data sources.
