摘　　要：在水库大坝施工中,对坝基进行帷幕灌浆是防渗处理的主要措施。概述了夹岩水利枢纽工程在泥质粉砂岩地层中进行帷幕灌浆施工试验的技术要求、孔位布置、灌浆材料、施工工艺、特殊情况处理,对试验成果进行了分析,提出了设计方案和施工参数优化建议,为后期坝段其他部位的灌浆施工提供了有效参数。Curtain grouting that stops leakages in the dam foundation is a major anti-seepage technique,which is often employed in the construction of reservoir dam.This paper briefly describes the geological,hydrological and meteorological conditions of the dam site area of the Jiayan Hydro-complex Project,and introduces the technical re⁃quirements,layout of the drilling holes,grouting materials,construction technologies,special cases treatments and experiment results analysis,puts forward curtain grouting design scheme and suggestions on optimizing construc⁃tion parameters.The analyzing results provide useful parameters for the grouting of other parts of the dam section.
