摘　　要：为了提高水利工程项目堤坝防渗与加固施工水平,确保水利工程长期稳定运行,提出了堤坝复合混凝土防渗与加固施工技术研究。首先,设计复合混凝土防渗墙,在堤坝地基中形成一道稳固性较高的防渗墙体;其次,采用双排布孔的布置形式,在堤坝两岸坡段上布设灌浆孔;在此基础上,利用劈裂灌浆加固技术,对水利工程项目堤坝复合混凝土进行加固施工。实验结果表明,该施工技术应用后,堤坝段落的渗透系数始终小于1×10^(-6)cm/s,满足水利工程项目堤坝防渗要求,能够提高防水性能与加固效果。In order to improve the level of anti-seepage and reinforcement construction of water conservancy projects,and ensure the long-term stable operation of water conservancy projects,a research on composite concrete anti-seepage and reinforcement construction technology for dams is proposed.Firstly,a composite concrete anti-seepage wall is designed to form a stable anti-seepage wall in the foundation of the dam;secondly,a double row layout of holes is adopted,and grouting holes are set up on the slope sections on both sides of the dam.On this basis,the splitting grouting reinforcement technology is used to reinforce the composite concrete of water conservancy project embankments.The experimental results show that after the application of this construction technology,the permeability coefficient of the dam section is always less than 1×10-6cm/s,meeting the anti-seepage requirements of hydraulic engineering projects,and can improve waterproof performance and reinforcement effect.
