摘　　要：堤坝在长期使用过程中易出现渗漏问题,因此,文章研究了一种基于劈裂灌浆技术的堤坝防渗加固施工技术,首先在堤坝两岸的边坡布设灌浆孔,然后采用高压喷射方式将水泥浆液灌注到灌浆孔内,形成劈裂土体,最后做好封孔与养护工作,从而得到起到堤坝防渗加固作用的防渗帷幕。实验结果表明,防渗加固施工后的堤坝内部浸润线较施工前大幅降低,其防渗性能得到显著改善,验证了该技术具有较好的应用效果。The dam is prone to leakage during long-term use.Therefore,this paper studies a dam anti-seepage reinforcement construction technology based on fracture grouting technology.Firstly,grouting holes are arranged on the slopes on both sides of the dam.Then,the cement slurry is poured into the grouting holes by high-pressure jet to form the fracture soil.Finally,the hole sealing and maintenance work are done well to obtain the anti-seepage curtain that plays the role of anti-seepage reinforcement of the dam.The experimental results show that the phreatic line in the dam after the anti-seepage reinforcement construction is significantly lower than that before the construction,and its anti-seepage performance is significantly improved,which verifies that the technology has good application effect.
