摘　　要：牛拦江-滇池补水工程是滇池流域水环境综合治理关键工程,是国家重大水利工程,由德泽水库、干涸泵站和输水线路等组成。水库大坝为面板堆石坝,坝址为薄层状缓倾角砂泥岩。本文针对德泽水库大坝区域水文工程地质特征,选择代表性灌浆试验区段开展帷幕防渗灌浆可灌性试验,并结合帷幕灌浆试验结果推荐各区段适宜的灌浆施工方法、灌浆材料及最优的浆液配合比等,为大坝坝基帷幕防渗灌浆施工提供可靠依据。The Niulan River-Dianchi Lake water replenishment project is a key project for the comprehensive management of the water environment in the Dianchi Lake Basin.It is a major national water conservancy project,consisting of Deze Reservoir,dry pumping station,and water transmission lines.The reservoir dam is a panel rockfill dam,and located on gently inclinedthin layered sandstone and mudstone.Based on the hydrogeological and engineering geological characteristics of the Deze Reservoir Dam area,representative sections were selected to conduct groutability tests for curtain anti-seepage grouting.Combined with the results of the curtain grouting test,suitable grouting construction methods,grouting materials,and the optimal slurry mix ratios were recommended for each section,which provide a reliable basis for the construction of curtain anti-seepage grouting for the dam foundation.
