【摘要】 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。更多还原

【Abstract】 In order to test the application effect of Diver automatic water level recorder in the study of hydrogeological parameters from pumping test data,a pumping test was carried out in the Liuli River area in Fangshan,Beijing. The characteristics of the original data from Diver and the manual measurement in the pumping test were compared,and the hydrogeological parameters were calculated based on Diver data.An average difference of the main well data between the Diver and the manual measurement was 0. 17 m,and the average difference of the auxiliary well data was 0. 02 m in the whole process of the pumping test.Finally,it was calculated that the value of the k was 91. 51 m/d,the value of the T was 1555. 72 m2/d and the value of the S was 0. 0314 based on the Diver data. Diver has the advantages of large amounts of continuous and accurate data to ensure that the hydrogeological parameters are performed correctly.更多还原
