| 摘 要： | 基于所建的横观各向同性层状弹性体系解,使用编制的基于该理论解的路面结构分析程序ANISOLAYER,分析了碎石材料横观各向同性特性对碎石底基层半刚性沥青路面结构的影响,对于软土地基来说,起到一定的加筋作用,随着粒状类材料水平模量的减小,可有效地降低半刚性基层底部的拉应力,使路面结构的受力状况更加符合实际,而且从路表弯沉、沥青层底部拉应变、半刚性基层底部拉应力以及路基顶部压应变来看,都使路面的寿命减小。 |
| 关 键 词： | 碎石底基层 横观各向同性 ANISOLAYER程序 半刚性沥青路面 |

| Abstract: | Based on the established cross-anisotropic layered elastic theory, and the structure analytical program ANISOLAYER, the influence of cross-isotropy granular on the structure of asphalt pavement is analyzed . For the soft subgrade, it has the role of reinforcement. With the decrease of granular horizontal elastic modulus, the tensile stress at bottom of granular sub-base will be reduced effectively. From the view of critical pavement responses, ineluding surface deflection of pavement, the tensile strain at bottom of asphalt layer , the tensile stress at bottom of semi - rigid base and the compressive strain at top of subgrade, the life of pavement is declined |
| Keywords: | granular sub-base cross-anisotropy ANISOLAYER program semi-rigid asphalt pavement |
