采用三维有限元法,分析了复合梁试件模型和实体桥面铺装模型中沥青混凝土铺装层表面的受力特性及其变化趋势。计算结果表明,复合梁模型和实体桥面铺装模型中的沥青铺装层表面的受力状态相同,变化趋势一致,采用试验可控性较好的复合梁试验能够模拟不同结构组合的桥面铺装层受力特性,为大跨径桥梁桥面铺装层结构设计、材料选择提供依据。
Abstract：The three-dimensional finite element method is adopted to analyze the mechanical characteristic and its variational trend on the surfaces of the asphalt concrete paving layer with a finite element model and an actual bridge deck model of a compound beam.The Computing results indicate that mechanical state of the compound beam is the same as that of actual bridge deck one,and its variational trend is consistent.So,the compound beam can be used to accurately simulate the mechanical characteristics of different structure combination in bridge deck pavement,which can offer some valuable theory base for the similar bridge deck pavement in structure design and material selection.
