摘　　要：北台上水库自建库至今,三副坝渗漏一直是该水库运行管理中的重要问题之一。2012年北台上水库安全鉴定,重点对三副坝区域进行了针对性的渗漏勘察。在综合分析前人勘察成果的基础上,采用钻孔压水试验和高密度电法对该坝区地下水流进行了详细勘察,查明三副坝区库水渗漏的途径和通道,评价其对水库大坝安全的影响,为分析坝区渗漏原因提供了参考,为该坝体除险加固工程设计方案的确定提供了建议。Since the construction of Beitaishang Reservoir,the seepage from its third auxiliary dam is an important problem in the operation management of the reservoir. During the safety appraisal made on the reservoir in 2012,a pertinent seepage investigation is emphatically made within the area of the third auxiliary dam. On the basis of a comprehensive analysis on the previous investigation data,a detailed investigation on the groundwater flow within that area is carried out with the water pressure test in borehole and the high density resistivity method,and then the leakage passages are identified,while their impacts on the safety of the reservoir dam are evaluated as well,which provide important basis for analyzing the causation of the sepage therein,thus provide some scientific suggestions for the design scheme of the risk-elimination and strenghtening of the dam.
