摘要
水泥土是在土中掺入水泥来改善土的力学性能的一种新型材料．利用静三轴UU试验，模拟水泥土在工程中的应力状态，测得水泥土在不同水泥掺入比和龄期下的粘聚力、内摩擦角、抗剪强度．对水泥土的抗剪强度进行系统的研究和探讨，结果表明，水泥土的抗剪强度随水泥掺入比增长而增大；而当掺入比达到33％后，水泥土抗剪强度增长趋于缓慢．此外，水泥土的后期强度较大，龄期为90d的水泥土抗剪强度比28d时增长26％～38％．
Cement soil is a newtype material composited by mixing the cement in soil to improve the mechanical property. Based on the UU triaxial test, the cohesive strength, internal frictional angle and shear strength of different cement ratio and age of cement soil can be obtained by simulation the state of stress in projects. The shear strength of cement soil was systematically investigated. The results show that the shear strength greatly increases with the cement ratio at the beginning , and gently increases while cement ratio is greater than 33%. The cement soil has large long-term strength and the shear strength of cement soil when age of 90 days increased 260%-38% from age of 28 days.
