| 摘 要： | 文章通过室内试验,对重塑黏土在不同含水量、不同排水条件和不同加载过程中的侧向应力情况进行了系统研究,分析了影响侧应力系数变化的条件,揭示了重塑黏土侧应力系数的变化规律。试验结果表明:加载情况下,侧应力系数的变化过程与孔隙压力增量的变化过程一致;土体在固结完成时,侧应力系数与饱和度呈正比例线性关系。

| Abstract: | Based on the laboratory experiment,the lateral stress in rebuilt clays is systematically studied with regard to different moisture content,drainage conditions and loading circles.Meanwhile,the conditions influencing the parameter of the lateral stress are analyzed,and the change rule of the parameter is revealed.The results show that the parameter of the lateral stress changes with the increment of the pore pressure under the loading and the parameter is directly proportional to the saturation degree when the consolidation process is finished. |

| Keywords: | rebuilt clay lateral stress parameter of lateral stress pore pressure saturation degree |
