为了给正交异性钢桥面板铺装技术提供可靠的、完善的理论依据,需要研究和分析钢桥面板、沥青混凝土铺装体系各层间结构,在日益增大的交通荷载以及环境等综合因素作用下的工作状态和应力应变特征。利用有限元方法对北盘江大桥进行了钢桥面铺装层受力分析,研究了沥青混凝土铺装层在行车荷载作用下应力、应变分布的变化规律。根据分析结果,提出北盘江大桥钢桥面铺装的设计指标建议。
In order to provide a reliable and perfect theoretical basis for the Orthotropic steel bridge deck pavement technology, it is necessary to study and analyze the structure of the steel bridge deck and the asphalt concrete pavement system. With the increasing traffic load and environment, Under the action of the state and stress and strain characteristics. The finite element method was used to analyze the mechanical behavior of Bei - Panjiang Bridge over the steel deck pavement. The variation of stress and strain distribution under the driving load of asphalt concrete pavement was studied. According to the analysis result, the design index suggestion of Bei Pan River Bridge deck decking is put forward.
