摘要
该文结合试验区域水文地质条件分析了抽水试验结果。利用抽水及水位恢复资料,采用几种实际应用较为广泛的求渗透系数的方法,求解试验区地层渗透系数,结果表明,在地质条件复杂区域利用解析法所求的参数误差较大,而采用数值法反演的参数精度较高且较可靠。研究区地层渗透系数取值为21.08m/d。
In this paper, the results of pumping test have been analysed combining with local hydrogeological condition. According to the data of pumping test and water level recovery, the permeability coefficient is obtained by several common methods at the test zone. The results show that the parameters which determined by analytical method are uncertainty, however parameters determined by numerical method are more exact in complex geological condition area.The permeability coefficient of the studied area is 21.08m/d.
