| 摘 要： | 沥青路面中层间接触状态非常复杂,它对路面的使用性能有直接影响。针对我国当前采用的典型半刚性沥青路面结构,采用GAMES多层弹性体系计算程序,系统分析了层间接触状态对表面弯沉、表面拉应变、面层内剪应力、沥青层底拉应变以及沥青层底剪应力的影响。分析结果表明:层间接触状态的变化对沥青层底的拉应变影响最为显著,其次为基面层间的剪应力,对路表的拉应变和基层底拉应变影响也较为明显;相对而言,路表弯沉、面层内最大剪应力对层间接触状态的变化不敏感。

| Abstract: | Bonding condition between adjacent layers is complicated in semi-rigid asphalt pavement,which can directly affect the road performance.By using a multi-layered elastic analysis program(GAMES) superior to BISAR,a study is conducted to analyze the mechanics response when changing the bonding condition between asphalt layer and semi-rigid layer.The results indicate that the bonding condition has the most significant effect on the tensile strain at the bottom of asphalt layer and the shear stress between the as... |
