| 摘 要： | 长寿命沥青路面层间接触状态对路面的使用性能有直接影响。文章针对典型长寿命沥青路面结构,采用BISAR 3.0多层弹性体系计算程序,系统分析了层间接触状态对长寿命沥青路面表面弯沉、沥青层底拉应变、路基顶压应变以及面层最大剪应力的影响。分析结果表明：层间接触状态的变化对长寿命路面沥青层底的拉应变和路基顶面压应变的影响最大,对路表弯沉的影响也较为明显;相对而言,对面层最大剪应力影响不明显。

| Abstract: | Bonding condition between layers of long-life asphalt pavement has a direct impact on performance.By using a multi-layered elastic analysis program BISAR 3. 0 to a typical long-life asphalt pavement, a study is conducted to analyze the mechanics response of the surface deflection, the tensile strain at the bottom of asphalt layer, subgrade compressive strain and the maximum shear stress in surface layer.Tha results indicate that the bonding condition has the most significant effect on the tensile strain at the bottom of asphalt layer and subgrade compressive strain,followed by the surface deflection.Relatively, the maximum shear stress in surface layer not sensitive to the change of the bonding condition. |
