| 摘 要： | 针对路基不均匀沉降条件下路面结构破坏机理难以解析的现状，引入数值分析方法，建立了沥青混凝土路面结构对路基横向不均匀沉降力学响应的有限元模型，重点针对路基两侧沉降、一侧沉降和中心沉降3种不均匀沉降形式进行分析，主要研究不均匀沉降量及路面结构参数对路面结构破坏的影响。

| Abstract: | The finite element model of mechanical response for the differential settlement of as- phalt concrete pavement structure was established by numerical analysis method in allusion to explain the situation that the failure mechanism of bed differential settlement which was hard to explain, and the set- tlement modes were analyzed in point for both sides of yen settlement and bed parameters were researched as pavement structure. bed, the side of bed and the center, different une- the primary influence factors to explain breakage of |
