摘　　要：以某高速公路双向六车道中等跨径桥梁中的钢混组合盖梁为研究对象,阐述了结构设计情况,建立了钢混组合盖梁有限元模型,计算结果表明:盖梁钢外壳作为永临结构在浇筑混凝土状态下受力最为不利,最大Mises应力为140 MPa;在成桥状态下盖梁钢外壳应力得到明显改善,同时混凝土应力水平相对较低,施工过程和成桥状态下盖梁最大应力和变形均满足规范要求。This article takes the steel-concrete composite cover beam of a medium span bridge in a two-way six lane highway as the research object,elaborates on the structural design situation,and establishes a finite element model of the steel-concrete composite cover beam.The calculation results show that the steel shell of the cover beam,as a permanent structure,bears the most unfavorable stress in the pouring concrete state,with a maximum Mises stress of 140.0 MPa.In the completed bridge state,the stress on the steel shell of the cover beam has been significantly improved,while the stress level of the concrete is relatively low.The maximum stress and deformation of the cover beam during the construction process and in the completed bridge state meet the requirements of the specifications.
