摘　　要：阁老湾水库大坝主河床段及右岸段坝基地层为厚层粗粒土,且具强透水性,存在渗透稳定隐患。水库运行多年后发现主河床段坝基现已发生变形。文中对该坝基存在的渗透变形类型及水力比降进行了评价,并提出了合理的施工措施。经工程处理后,可确保坝体处于稳定运行状态,使该水库继续发挥其可观的社会效益和经济效益。The dam foundation of Gelaowan Reservoir’s main section and right bank mainly consists of coarse grained soil which has high water permeability,so it poses a danger of seepage stability.After years’operation,the dam foundation of the main section has undergone deformation.This essay evalues the type of permeability deformation and hydraulic gradient,and offers feasible construction measures.The construction can make sure that the dam will remain stable and the reservoir will keep on benefiting both the economy and the society.
