| 摘 要： | 论证了采用多孔介质理论描述处于自然环境中沥青路面的合理性，并基于饱和多孔介质理论，建立了轴对称瞬态动力分析的有限元模型，给出了有限元分析的荷载条件、边界条件和材料参数；分析了动态荷载作用下，饱和状态沥青路面不同应力分量的时程变化情况．结果表明，动态荷载作用下，路面结构内部应力场、位移场具有波动性质；同时产生了不可忽视的孔隙水压力，且出现了正、负逆转，这种孔隙水压力的反复作用最终将导致沥青混合料出现松散破坏．

| Abstract: | The coupled water-loading action is one of the primary factors of initial failure for asphalt pavement.At first,porous media theory was used to describe asphalt pavement in the environment,whose rationality was also demonstrated.Then,based on saturated porous media theory,transient dynamic analysis of axisymmetric finite element model for saturated asphalt pavement was built,whose corresponding loading condition,boundary condition and material parameters were given at the same time.Finally,the time history ... |
