通过一系列恒定应变率的单轴压缩试验,对高岭土的年代效用和粘性进行了研究.实验中观察到了未掺水泥的高岭土的显著的蠕变变形.经过恒定载荷作用一定时间后重新以恒定应变速率加载时,掺水泥的高岭土在较大的应力范围内有很陡的应力-应变关系曲线.实验发现,通过掺水泥,高岭土的湿陷和蠕变变形明显降低.未掺水泥和掺水泥的高岭土,屈服后的e-log(σ′ν)关系为线性关系,且与饱和期和/或养护时的应力无关 Through a series of uniaxial compression tests at constant strain rates, the age-effectiveness and viscosity of kaolins were studied, and significant creep deformation of kaolin without cement was observed in the experiment.After constant load for some time, At a high rate of loading, the cement-laden kaolin has a very steep stress-strain curve over a wide range of stresses. It has been found that the cementing and creep deformations of kaolin are significantly reduced by the addition of cement. Kaolin, the e-log (σ'ν) relationship after yield is linear and independent of the stress at saturation and / or curing
