潜水-微承压含水层水文地质参数求解方法研究

摘要

潜水-微承压含水层水文地质参数是正确评价山西临汾涝洰河生态建设工程,确定水库渗漏量的重要依据.以涝河河谷中段C6典型抽水试验为基础,基于含水层试验(Aquifer Test)专业软件,分析多种方法下获取的潜水-微承压含水层水文地质参数.结果表明,考虑潜水重力释水的Boulton法和水位恢复法求得的水文地质参数稳定可靠,可为后期水文地质数值模拟提供基础数据.%The hydrogeological parameters of phreatic-feeble confined aquifer are important indexes to accurately evaluate LaoJu River Ecological Construction Project in Linfen,Shanxi,and the key basis to confirm reservoir leakage.On the basis of C6 hole pumping test in the middle of Laohe River,the hydrogeological parameters of phreatic-feeble confined aquifer obtained by various methods are analyzed by Aquifer Test software.The result shows that the parameters calculated by the Boulton method which considering phreatic and reliable aquifer gravity water release and the water level recovery method are stable and reliable,which can provide basic data for later hydrogeological numerical simulation.
