摘要
针对目前隧道复合式沥青路面表面出现受拉破坏的现象,为了揭示沥青层表面破坏的力学机理,运用三维有限元方法建立隧道复合式路面结构与荷载模型,分析垂直荷载与水平荷载综合作用下沥青层表面的拉应力,得出了影响沥青层表面拉应力的影响因素。并据此提出延长隧道复合式路面使用寿命的措施。
Aiming at the phenomenon of surface damage of compound asphalt pavement in road tunnel, to find out the damage mechanism of compound pavement, the authors analyze the stress on the surface of the compound pavement in road tunnel, taking full consideration of the combined effect of vertical and level load and using three-dimension finite method, as well as impact factors on the surface stress on the based of which, some methods to increase the service life of compound pavement in road tunnel are proposed.
