| 摘 要： | 利用基于割离井法的流量时间配线法反求抽水过程和井回灌过程的水文地质参数，并与泰斯法、裘依公式法、割离井公式法的求解结果进行了对比。结果表明，潜水含水层水文地质参数的求解选用流量-时间配线法求解精度高，可以减少繁琐的计算，结果是可靠的；对等水文地质条件下，井抽水过程求得的水文地质参数稍大干井回灌过程求得的水文地质参数，但可以用抽水过程求参方法近似求解井回灌过程的水文地质参数；运用泰斯法近似计算潜水含水层水文地质参数结果显著偏大，建议一般不予采用。

| Abstract: | Using the method of discharge-time matching line which is based on the isolated well method, this paper computes the hydrologic-geologic parameters in the process of pumping and replenishing water, and contrasts its results to those of the methods of Theis, Dupuit and isoiated well. The results explain that the discharge-time matching line method is ideal for its high accuracy, convenient calculation and r.eliable results in computing the phreatic parameters. Under the same hydrologic-geologic condition, the phreatic parameters of well pumping is little higher than that of well artificial replenishment, but the method used for pumping water process can be used to get approximatively the phreatic parameters of artificial replenishing process. The calculated results of the hydrologic-geologic parameters of phreatic aquifer by using the Theis method are obviously on the high side, so it is not suggested to adopt generally. |
