摘　　要：近年来,许多城市的道路交通相继出现了饱和现象,交通拥堵逐年加剧。为缓解交通现状,修建城市快速路成为当今社会的主流。在城市快速路的修建过程中,如何选择经济适用、耐久合理的结构形式至关重要。依托上海某工程,以某跨路口桥梁的结构选型为例,从受力性能、适用性、经济性、美观性等方面进行结构选型分析,总结对比了连续钢板组合梁、连续钢箱组合梁和连续钢箱梁等结构形式的特点和适用情况,为相近工程的结构选型提供参考。In recent years,the road traffic in many cities has been saturated,and the traffic congestion is getting worse year by year.In order to ease the situation,the construction of expressway is meaningful.In the process of construction,how to choose the best structure form is very important.Based on a project,this paper takes the structural selection of a joint bridge as an illustration,analyzes the structural selection from the aspects of applicability,economy,aesthetics and so on,summarizes and compares the characteristics and application of steel plate composite beam,steel box composite beam and steel box beam,provide reference for relevant items.
