既有公路桥梁有轨电车改造关键技术

Critical tramcar transformation technologies of existing highway bridge

总结了公路或市政桥梁既有桥梁有轨电车改造的三种模式,并分析了其特点和适用条件,从既有桥梁改造评估入手,分析了公路、市政、有轨电车荷载对梁部内力的影响,以及梁部及桥墩结构刚度指标,给出了具体建议,提出了合理轨道结构等桥梁改造技术方案。

The paper summarizes three kinds of tramcar transformation models of highway or municipal existing bridge,analyzes their features and application conditions. Starting from existing bridge transformation evaluation,it analyzes the impact of highway,municipal and tramcar loads upon internal beam force,explores beam and pier structure rigidity indicators,shows specific suggestions,and puts forward rational track structure and other bridge transformation technology schemes.
