为了减少因分层抽水而造成的钻探施工过程中的困难,长期以来水文地质工作者在探讨用混合抽水试验确定含水层水文地质参数的方法。在已有的方法中,多采用稳定流混合抽水试验加做某些辅助工作的办法,以确定含水层水文地质参数。但由于稳定流抽水试验本身在理论上的缺陷,尤其是因为有的方法需要 In order to reduce the difficulties in drilling construction caused by stratified pumping, hydrogeologists have long been discussing ways to determine hydrogeological parameters of aquifers using mixed pumping tests. In the existing methods, more stable mixed flow pumping test plus some auxiliary work to do to determine the aquifer hydrogeological parameters. However, due to the theoretical flaws in the steady flow pumping test itself, especially since some methods require
