水泥土力学性能的试验研究

利用内蒙古河套粉质粘土拌制水泥土,掺入比分别取5%、10%、15%、20%、25%,养护龄期取7 d、28 d、60 d、90 d,通过单轴受压试验,取得了水泥土无侧限抗压强度、应力-应变关系的变化规律,并分析了对其影响的因素,提出了这种水泥土的单轴受压下应力-应变全曲线本构方程,定量的分析了龄期、水泥掺入比对水泥粘土的力学性能的影响,为其应用于实际工程提供实验依据.

Study on Mechanical Behaviors of Soil Cement

The soil cement was made from cement and silty clay of Hetao Irrigation District. The mixing amount of cement is 5%,10%,15%,20%,25% respectively in the lab,The curing age is 7 d,28 d,60 d,90 d respectively. the uniaxial compressive strength without lateral confinement and the stress-strain relationship of the specimens were measured,and the influence factors were analyzed. The equation of stress-strain curve of the soil cement was established under the condition of uniaxial compression. In addition,the infl...
