| 摘 要： | 为了研究车辆荷载作用下排水基层路面的动力响应,同时考虑车速和轴载的影响,采用移动加载的方法,对不同工况下沥青混凝土路面进行了快速Lagrange有限差分分析.结果表明,路面弯沉并未因排水基层的低模量而增大,峰值甚至有所减小；排水基层的存在减小了底基层底部的动应力,可以抑制反射裂缝的产生；弯沉及动应力均随车速的增大而减小...

| Abstract: | In order to study the dynamic response of asphalt concrete pavement with permeable base under vehicle loads,based fast Lagrangian finite difference method,the dynamic analysis of asphalt concrete pavement under various conditions is conducted,considering the influence of moving vehicle load and different speed.The results show that the pavement dynamic deflection did not increase though the modulus of permeable base is low.The permeable base reduced the dynamic stress at the bottom of the subbase,which can ... |
