| 摘 要： | 我国新建道路沥青路面是以双轮组单轴载100 kN(BZZ-100)为标准轴载,采用双圆均布荷载作用下的多层弹性理论进行设计的,而汽车实际施加给路面的是移动荷载。通过建立半刚性基层路面的三维有限元分析模型,对汽车匀速行驶及制动情况下路面的动态响应进行了有限元分析,得出了荷载正下方不同深度处节点竖向位移、竖向压应力、水平应力、竖向剪应力及水平剪应力的时间历程曲线,并与静载作用下的计算结果进行了对比分析。

| Abstract: | The asphalt pavement of newly-built roads in China adopts the double group uni-axle load 100 kN(BZZ-100)as the standard axle load,which is designed by the multi-layer flexible design theory under the effect of double-circle uniformly distributed load.But the load that vehicle imposes on the road surface is the moving load.FEM analysis on the dynamic response of road surface in the cases of vehicle running at common speed and at the state of baking is carried out,through establishing the three dimensional dy... |
