摘　　要：黄金峡水利枢纽基础岩体较完整,但断层、裂隙较发育,局部还存在不稳定块体,会造成局部应力不均、不均匀变形等问题,对大坝的基础稳定性、承载力带来不利影响。为提升围岩完整性与承载力、保证地基稳定,在水利工程基础处理时须对地质缺陷部位进行专项处理设计。文章通过对黄金峡水利枢纽坝体基础揭露的各种地质缺陷进行系统分析、专项设计、分类处理,通过补强固结灌浆设计与应用,使基础满足了大坝建设的各项要求,保证了工程的质量与安全,也证明了补强固结灌浆在水利工程基础处理中的作用,对类似水利工程施工具有借鉴意义。The foundation rock mass of Huangjinxia Water Conservancy Project is relatively complete,but the faults and fissures are relatively developed,and there are still unstable blocks in the local area,which will cause problems such as uneven local stress and uneven deformation,which will adversely affect the foundation stability and bearing capacity of the dam.In order to improve the integrity and bearing capacity of surrounding rock and ensure the stability of foundation,it is necessary to carry out special treatment design for geological defects in the foundation treatment of water conservancy projects.Through the systematic analysis,special design and classification of various geological defects exposed by the dam foundation of Huangjinxia Water Conservancy Project,through the design and application of reinforcing consolidation grouting,the foundation meets the requirements of dam construction,ensures the quality and safety of the project,and also proves the role of reinforcing consolidation grouting in the foundation treatment of water conservancy projects,which has reference significance for similar water conservancy construction.
