| 摘 要： | 利用在常规三轴仪的基础上改制而成的应力控制式三轴仪进行了加(卸)荷作用下软黏土变形特性的室内试验研究,得到了以下的结论:(1)在加荷载和卸荷载大小相同的情况下,卸荷过程中的变形量比加载过程中的变形量小,约为加载过程中的变形量的十分之一；(2)当卸荷比例比较小时,试样的回弹变形量非常小；(3)当卸荷比例达到某一定值以后,...

| Abstract: | The displacement-time relationship curves are got from laboratory tests for the deformation character analysis of the soft clay in unloading condition.The stress control triaxial compression apparatus is used and remade from the strain control compression apparatus.The following conclusions are gained from the analysis of the test results:(1)when the amount of the loading and the unloading are the same,the amount of the deformation produced in the unloading process is much smaller than the amount of the def... |
