摘　　要：苏丹麦洛维大坝工程所在地区岩石裂隙较发育,并且大部分为细微裂隙,透水率大,可灌性不好。为实现良好的可灌性和固结、防渗效果,经过研究分析,使用超细水泥,并掺加膨润土和高效减水剂配制稳定浆液,该稳定浆液具有良好流动性和稳定性,在该地质条件下可灌性好,应用于该大坝混凝土趾板灌浆工程中,达到了灌浆效果。Rock fractures are relatively developed,and most of them are micro fissures with high water permeability and poor groutability in the location of Milloway Dam Project.Superfine cement is used,and it is mixed with the bentonite and high rang water reducing agent to prepare stabilized grout through research and analysis in order to achieve excellent groutability as well as consolidation and seepage control effect,the stabilized grout has excellent mobility and stability.The groutability is excellent under the geological conditions,which can be applied to the dam toe slab grouting project with excellent concrete grouting effect.
