摘　　要：灌浆加固技术在水利工程领域的应用非常广泛,对低渗性不良地质体进行灌浆理论研究具有重要价值。文中通过添加固化剂和表面活性剂的方法对环氧灌浆材料进行改性,并利用有压渗透试验模型,测试了自配土和纯黏土两种低渗性不良地质体中改性环氧浆液灌浆的渗透距离,参考测试数据对Maag公式进行改进,结果显示改进的magg公式可以较好地反映灌浆压力和浆液渗透距离之间的关系。Grouting reinforcement technology is widely used in the field of water conservancy engineering.It is of great value to study grouting theory of low permeability geological bodies.Through the method of adding curing agent and surfactant to modify epoxy grouting material and using pressure permeability test model,the paper measure the permeability distance of modified epoxy grouting fluid into two kinds of low permeability geological bodies of self-made soil and pure clay,refers to the measure data to improve Maag formula,the results show the improved magg formula can reflect well the relationship between the grouting pressure and grout penetration distance.
