摘要
抽水试验是获得水文地质参数最直接且最有效的方法,但由于水文地质参数的计算方法繁多,试验人员对计算方法的选择很大程度上决定了参数的合理与否。论文通过对某地铁工程抽水试验进行分析,对比各计算方法的结果,对抽水试验水文地质参数的确定提出了建议,推荐采用AquiferTest软件Theis配线法或cooper-jacob直线图解法进行水文地质参数的计算。
Pumping test is the most direct and effective method to obtain hydrogeological parameters, but because there are many calculation methods of hydrogeological parameters, the choice of calculation methods by testers largely determines the rationality of parameters. Through the analysis of pumping test of a subway project, this paper compares the results of various calculation methods, and puts forward suggestions on the determination of hydrogeological parameters of pumping test, recommends using Theis wiring method with AquiferTest software or cooper-jacob linear diagram method for calculating hydrogeological parameters.
