In order to study the influence of stress path on the constitutive relations for reshaped clay,the triaxial compression tests under stress paths with drainage in cases of increased,constant and decreased mean normal stress and undrained conventional triaxial compression test have been carried out,the stress-strain relations under the four stress paths are obtained.
为探讨应力路径对重塑粘土本构关系的影响,进行了增、等、减排水和常规三轴压缩不排水应力路径下的三轴压缩试验,获得了四种应力路径下重塑粘土的应力应变关系,采用数值建模方法通过可视化分别给出了四种应力路径下整个应力场中的剪切和体积三维变形曲面,并给出了四种应力路径下的剪切和体积屈服轨迹。
