【摘要】 南京长江第二大桥采用正交异性钢箱梁结构 ,桥面铺装层在国内首次采用环氧沥青混凝土材料。本文将正交异性钢桥面板、铺装层作为受力整体 ,建立有限元分析模型 ,研究铺装层内受力变形特点 ,提出桥面铺装层破坏指标。研究铺装层参数、钢箱梁有关设计参数对于铺装层受力的影响。为桥面铺装层材料选用、钢箱梁结构构造设计及车道划分提供理论依据。更多还原

【Abstract】 The orthotropic steel?girder structure is adopted in Nanjing Second Yangtze River Bridge, the epoxy asphalt concrete is first used as pavement material in China The finite element model is established in the paper uniting the orthotropic steel deck and pavement, the response of the pavement is researched and the damage indexes of the pavement are presented The effects of pavement parameters and steel?girder design parameters on the stress and deformation of the pavement are studied The researches provide the theoretic base for the choice of pavement material, steel?girder structural design and driveway division更多还原
