摘 要: 介绍了室内模拟交通荷载作用下路面和软土地基共同作用的模型试验,根据试验结果得出了路面板的弯沉、应力以及永久变形。采用弹粘塑性有限元理论分析了路面在竖向静荷载和循环荷载作用下的应力和变形特性,并与试验结果进行了比较。 The model experiment of pavement and soft clay ground interaction under traffic loads are introduced. According to the experimental results, the displacements,stresses and permanent deformations of pavement are obtained.Stress and deformation characteristics of pavement under static and cyclic loads are analyzed with the elasto viscoplastic finite element theory.The results of calculation and experiment are compared.
