摘　　要：帷幕灌浆是将浆液灌入岩体或土层的裂隙、孔隙,形成连续的阻水帷幕,以减小渗流量和降低渗透压力的灌浆工程。本文以大唐乡城古瓦水电站大坝右岸趾板帷幕灌浆施工为例,对帷幕灌浆在变质砂岩夹板岩地层施工中遇到的问题进行了探讨,旨在对类似工程施工提供参考借鉴。Curtain grouting is a grouting project in which the slurry is poured into the cracks and pores of rock or soil layer to form a continuous water blocking curtain to reduce the seepage flow and osmotic pressure.Taking the curtain grouting construction of right bank toe slab of Datang Xiangcheng GuWa hydropower station dam as an example,this paper discusses the problems encountered in the construction of curtain grouting in metamorphic sandstone splint rock strata,so as to provide references for similar projects.
