摘　　要：对改性环氧树脂加固试块进行立方体抗压强度、棱柱体抗压强度、抗折强度等基本力学性能实验.通过对实验结果进行分析,得到不同配合比的改性环氧树脂在不同固化时间下对砂土加固的效果.当水性聚氨酯质量分数为20%时,加固的综合性能最好.为以后改性环氧树脂在地基加固中的应用提供参考价值.The basic mechanical properties such as cube compressive strength,prism compressive strength and flexural strength were tested.Based on the analysis of the experimental results,the effect of modified epoxy resin with different mixing ratio on strengthening sand under different curing time was obtained.When the content of waterborne polyurethane is 20%,the reinforcement has the best comprehensive properties.It provides reference for the application of modified epoxy resin using in foundation reinforcement.
