摘　　要：黔中水利枢纽工程位于岩溶发育地区,混凝土面板堆石坝最大坝高157 m,水库总库容10.89亿m3,库首防渗帷幕灌浆总量235 000 m,工程量巨大,地质条件复杂。本文介绍了在该工程库首左岸泥岩、泥灰岩地层中进行帷幕灌浆施工试验的要求、布置、材料、工艺、特殊情况处理及试验成果,并提出了设计方案和施工参数优化建议。The Qianzhong hydro-junction project is locate on the district of Karst grown. The maximum dam height of the concrete face rockfill dam is 157 m and the total storage capacity of the reservoir is 10.89 ×108m3.The total curtain grouting quantity for the reservoir head seepage prevention is 235×103m3. Then the engineering quantity is large and the geological condition is complex. The paper introduces the requirements, layout, material,technique, especial trouble treatment and experiment result of the curtain grouting construction experiment in the mudstone and marl layer of the left bank of reservoir head region, puts forward the design scheme and optimization suggestion of construction parameter.
