摘　　要：针对东台子水库坝址区深厚覆盖层的地层结构及物质组成等特点,为了确定不同深度含水层渗透特性,结合工程设计,通过分析研究,制定了单井同井径分层分段抽水试验方案,并通过工程现场实施,取得良好效果。详细论述了抽水试验方案内容及方案实施过程中的关键技术问题、主要技术措施,有效地解决了传统分层抽水试验中经常出现的技术问题,相比其它方案节省了投资,并取得更加准确、可靠的抽水试验结果。According to the characteristics of stratum structure and material composition of deep overburden in the dam site area of Dongtaizi reservoir,in order to determine the permeability characteristics of aquifers with different depths,layered pumping test scheme of single well with the same diameter is formulated after careful analysis and research in combination with the project design,and it has been implemented at project site and achieved good effects.This paper discusses in detail the contents of the pumping test,the key technical problems and main technical measures during implementation of the scheme,which effectively solves the technical problems frequently occurred in the traditional layered pumping test,saves the investment,and obtains more accurate and reliable pumping test results.
