Abstract
To address the challenge that rock mass uplift is prone to occur during grouting construction for earth-rockfill dams in areas with insufficient overburden thickness and poor rock mass stability,this paper carried out a systematic investigation from two aspects:optimization of packer selection and uplift control technology.The results indicated that both mechanical packers and inflatable packers with a relatively large diameter difference from the borehole opening could reduce grouting pressure loss.Moreover,the"hold-and-step pressurization"control strategy could effectively suppress rock mass uplift,thereby ensuring the safety and quality of foundation curtain grouting for earth-rockfill dams under thin overburden conditions.The paper provide reference value for curtain grouting construction in earth-rockfill dam foundation under similar geological conditions.关键词
