摘要
通过建立路基的离散元模型,数值模拟了盐渍土路基在荷载作用下的破坏响应,给出了组成路基颗粒在荷载作用后的位移大小和运动方向,并把路基划分成10层,对比分析了各层位移量的大小。
Through the establishment of discrete element model of subgrade, this paper carries out numerical simulation of destruction response of saline soil subgrade under load and gives displacement degree and movement direction of subgrade component granules under load. It also divides subgrade into 10 layers to carry out contrast analysis on displacement degree of granules in each layer.
