摘　　要：针对广州珠江黄埔大桥的结构形式,对钢箱梁桥面铺装体系进行三维有限元分析,分别研究铺装层厚度、钢桥面板厚度、横隔板间距、纵向加劲肋构造尺寸等钢箱梁桥面铺装体系的构造参数对铺装层最大拉应力、铺装层与钢桥面板层间最大剪应力和铺装层表面最大弯沉值等受力控制指标的影响。用此研究结果可指导珠江黄埔大桥钢箱梁桥面铺装层的设计。In the light of the structural form of Huangpu Bridge over Zhujiang River in Guangzhou, this paper makes the three-dimensional finite element analysis of the deck pavement system of the steel box girder of the Bridge and respectively investigates the influences of the structural parameters of the pavement system, such as the pavement layer thickness, steel deck plate thickness, diaphragm spacing, longitudinal rib stiffener size, on the controlled mechanical indices of the maximum tensile stress of the pavement layer, maximum shear stress between the pavement layer and steel deck plate and maximum deflection values of the pavement surface. The results of the investigation can be used for guiding the design of the pavement layer of the box girder.
