摘要

为从细观角度分析黄土的变形破坏机理，以取自遂川至大余高速公路的黄土为样本进行三轴压缩试验，并采用离散元法，分析三轴压缩过程中的颗粒位移场变化、力链分布特征及能量演化规律。结果表明，室内试验与模拟试验结果高度吻合。黄土三轴压缩过程可分为3个阶段，弹性压缩阶段颗粒侧向位移小，内部力链密集且均匀，能量以应变能形式储存；塑性屈服阶段颗粒侧向位移增大，中部左右两侧力链断裂而中心区域力链密集，应变能继续累积并伴随少量能量耗散；应变软化阶段颗粒滑移形成剪切带，剪切带内力链断裂，力链网络稀疏，耗散能持续增加。柔性边界下，试样鼓胀现象明显，边界处力链分布均匀，而刚性边界下，试样无鼓胀现象，边界处存在接触盲区。相比于低围压，高围压对黄土颗粒的约束作用强，颗粒侧向位移被限制，颗粒间不易发生相对滑移，使力链不易破坏并且力链网络密集，从而耗散能占比低。
