下伏采空区的柔性基层沥青路面力学分析

针对地下采空区的分布,建立了ANSYS模型,分别研究了典型柔性基层和半刚性基层路面结构下采空区在6种不同位置时,路表弯沉、路面各层间应力应变的变化情况,从而得出了地下采空区对路面结构的影响规律,并对这两种不同的结构类型做出分析和比较.

On the mechanics analysis of the granular material asphalt pavement in the tackling subsiding ground

Aiming at the distribution of the tackling subsiding ground,the paper establishes ANSYS model,analyzes the changing situations of the stress-strain of the pavement deflection and all pavement layers for the typical flexible asphalt pavement and the semi-rigid base at six different positions,and concludes the influential rules of the tackling subsiding ground on the pavement structure,and has an analysis and comparison of the two different structural types.
