| 摘 要： | 模拟低掺量水泥土在工程中的应力状态，利用静三轴CU试验研究了水泥掺入比小于5 %的低掺量水泥土的应力-应变关系及强度特性，探讨了在不同水泥掺量情况下水泥土抗剪强度指标的变化规律，分析了素土和水泥土的变形破坏模式。结果表明:水泥土强度随水泥掺量增加而提高，当水泥掺入比大于15 %时，水泥土的强度和抵抗变形的能力较素土有显著的增强。

| Abstract: | Through simulation of the stress state of low proportional soil-cement in engineering,this paper studies stress-strain relationship and strength property of soil-cement with cement proportion less than 5% through static triaxial CU test,explores the rule of shear strength indicator changes of soil-cement under different cement proportions,and analyzes the failure mode of plain soil and soil-cement.It is indicated from the result that soil-cement strength improves with the increase of cement proportion.When cement proportion is higher than 1.5%,soil-cement strength and deformation resistance are largely improved compared to plain soil. |

| Keywords: | triaxial test soil-cement stress strain relationship shear strength |
