Abstract: In the aim of tackling technical difficulties in anti-seepage and reinforcement of complex unfavorable geological bodies under water head above 200 m, CW high performance epoxy resin grouting materials of high strength, high permeability, high adhesion, large-range adjustable operation time and environmental friendliness, have been prepared. Moreover, elaborated cement-chemical compound grouting control process and equipment for different grouting bodies and conditions have also been developed. A complete set of treatment technology for unfavorable geological bodies under high water head has been constructed. The technology has been successfully applied to Xiluodu, Xiangjiaba, Qingyuan pumped storage and other water conservancy and hydropower projects, and can also be applied to transportation, mining and other industries, implying broad application prospects.

Key words: epoxy resin grouting materials, high water head, unfavorable geological bodies, interlayer and internal staggered zone, fracture zone, alteration zone, anti-seepage and reinforcement
