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。
Based on the hydrogeological conditions in the test area, the pumping test results are analyzed. Utilizing the data of pumping and water level recovery, several kinds of practical application of permeability coefficient method are widely used to solve the permeability coefficient of formation in the test area. The results show that the parameter error is large in analytic method of complex geological conditions, The parameters of the method inversion are more accurate and reliable. The permeability coefficient of the study area is 21.08m / d.
