摘　　要：结合工程实际,在饱水养护条件下,进行夯实水泥土无侧限抗压强度室内试验,研究小龄期水泥土无侧限抗压强度随养护龄期、水泥掺入比的变化规律,分析水泥土强度与龄期、水泥掺入比的定量关系,结合试验数据拟合得出不同水泥掺入比条件下水泥土强度与龄期的经验公式,并探讨水泥土轴向应力应变曲线的变化趋势与水泥土的破坏方式随养护龄期的转变,从而进一步完善饱水条件下小龄期夯实水泥土强度演化发展理论,促进水泥土在实际工程中的推广应用,对工程施工有一定指导意义。The laboratory experimental studies of the unconfined compressive strength of the saturated compacted cement mixed soils with short curing age.The relationship among the compressive strength of the samples,curing age and cement to soil ratio are investigated and the empirical correlations are obtained.The axial stress strain relationship of the cement mixed soils with the curing ages and the failure modes are examined.The results can be used in the engineering applications.
