| 摘 要： | 旧水泥混凝土路面进行沥青加罩时，加铺层与旧板的连续性对加铺后路面各结构层的力学特性，以及出现反射裂缝的可能性会有较大的影响。由于传统的多层弹性体系理论不能计算带接(裂)缝的路面结构。因此本文利用三维有限元的计算工具，分析了在车辆荷载作用下，水泥混凝土不同的沥青加罩结构，在层间接触条件不同时的力学响应，并得出一些有意义的结论。

| Abstract: | When old cement concrete pavement is repaved with overlay of asphalt mix, both the mechanical characteristics of all structure layers and the possibility of reflection cracking are mainly influenced by the continuity between the overlay and old pavement. In view of the incapability of traditional elastic multi layer theory for pavement structures with cracks, the 3 D FEM method was used to analyze the mechanical response of the multi layer system to traffic load. Overlays on cement concrete pavement with different interface conditions were considered in the analysis, resulting in significant results. |
