摘要
在对大跨径混凝土桥梁整体结构有限元分析的基础上 ,应用子模型法对大跨径混凝土斜拉桥梁桥面板局部进行了有限元结构受力分析 ,分析轴向不同位置桥面板结构的变形特点及应变状态 ,并与所建立的普通路面模型基层弯沉进行对比分析 ,从桥面板弯沉及应变角度分析大跨径混凝土箱梁桥面铺装对沥青混凝土的性能要求 ,并总结了大跨径桥梁桥面铺装的力学分析方法 ,为大跨径混凝土桥梁沥青桥面铺装的设计提供参考依据。
Based on finite element analysis for the whole concrete structure of bridge with long span,a submodeling method is used for finite element structural loaded analysis.Characteristic of deformation and state of strain of bridge in axial different location are analyzed,and compared with established model of deflection of common pavement base course.The performance requirement of pavement of bridge with long span box beam on saphalt concrete is analyzed from the viewpoint of deflection.The method of mechanical analysis used for overlay of bridge with long span is summarized to be reference for designing overley of bridges with long span.
