| 摘 要： | 路基路面是一整体,路基不均匀变形会导致路面开裂。为了分析路基不均匀变形引起路面结构的应力、应变变化过程,应用ABAQUS来分析青藏公路路面结构对路基不均匀变形的适应性,建立了路基不均匀变形引起路面结构破坏的响应模型。结果表明,路基变形量在3cm以内路面各结构层的弯拉应力在其容许范围内,道路结构是安全的。

| Abstract: | Subgrade pavement is as a whole.Pavement cracking occurrs due to subgrade uneven deformation.In order to analyze the changes of stress and strain of pavement structure caused by subgrade uneven deformation,this paper analyzes the adaptability of Qinghai-Tibet Highway pavement structure to subgrade uneven deformation using ABAQUS,and establishes response model of pavement structure failure due to subgrade uneven deformation.It is shown that flexural stress of each pavement layer is within the permissible range when subgrade deformation is no more than 3cm.In this condition,pavement structure is safe. |

| Keywords: | pavement structure flexural stress subgrade uneven deformation adaptability |
