摘　　要：车辆荷载对路面的作用是导致路面病害的主要原因.以某道路改建工程为依托,通过大量的室内外实验,把实验的数据借助ANSYS力学分析软件进行路表弯沉、应力等静力学分析,得到最大值出现位置和应力变化趋势.考虑到路面上车辆行驶的运动特点,对车路系统进行了动力学分析,得到位移最大值及应力随时间的变化规律,为道路病害的预防提供了理论依据.The main reason for pavement disease is vehicle load. We did lots of experiments based on a road reconstruction project and then through the static analysis of road surface deflection and stress with ANSYS,we can get maximum position of road surface deflection and variation tendency of stress. Taking into account the movement characteristics of the vehicles on the road, we got the maximum displacement and stress variation rules with time through the dynamic analysis of vehicleroad system. The research results will provide a theoretical basis for the prevention of pavement disease.
