摘　　要：以某一城市有轨电车工程为背景,采用双线预应力混凝土U梁和双线钢-混凝土组合U梁2种方案进行结构设计,并对2种结构形式进行有限元建模分析。在此基础上,探讨双线U梁在有轨电车高架桥中的适用性。所得结论可为类似工程提供一定的指导作用。Taking an urban tramcar project as the background,two schemes of double-line prestressed concrete U-beam and double-line steel-concrete composite U-beam are used for the structural design and the finite element modeling analysis is carried out for the two structural forms.On the basis,the applicability of double-line U-beam in tramcar viaduct is discussed.The conclusions obtained can provide some guidance for similar projects.
