摘要
采用BISAR 3.0计算软件对不同轮载和层间接触状态下沥青路面路表弯沉、面-基层间正应力和剪应力、路基顶面压应变进行分析。结果表明,不同层间接触状态对路面结构力学响应的影响与轴载和胎压有很大关系,同时层间黏结作用的缺失和超载将大大增加车辙、拥包和推移出现的概率。
Asphalt pavement surface deflection,normal stress and shear stress of the interface between surface and base courses as well as the compression strain on top of subgrade are analyzed by BISAR3.0.The results show that influences of different interface bonding conditions on pavement structure mechanical responses have close relationship with axle load and tire pressure.Meanwhile,the lack of bonding function between interfaces and overloading will greatly increase the probability of rut,upheaval and translation diseases.
