摘　　要：针对200 m以上水头下复杂不良地质体的防渗补强技术难题,研发了高强度、高浸润渗透性、高粘结性、可操作时间长、胶凝时间精确可调和环保性能优良的CW系高性能环氧树脂灌浆材料,开发了针对不同受灌体和灌浆工况的水泥-化学复合灌浆精细控制工艺和配套灌浆设备,并形成了高水头下不良地质体处理成套技术。该技术已成功应用于溪洛渡、向家坝、清远抽水蓄能等重点水利水电工程,也可推广应用到交通、矿山等行业,具有广阔的应用前景。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.
