摘　　要：随着国内城市轨道交通的发展,越来越多的高架线投入运营。地铁高架结构以简支梁为主,结构形式主要分为整体箱梁、U形梁、小箱梁等常用类型。选择一种合适的梁型,不仅要考虑经济性和美观性,还要考虑受力是否合理。文章以长株潭西环线一期工程(长沙轨道交通3号线南延线)为依托,分析了简支梁结构形式,优化其刚度及变形,可为后续简支梁设计提供参考。With the development of urban rail transit in China,more and more elevated lines are put into operation.The elevated structure of subway is mainly composed of simply supported beams,and the structural forms are mainly divided into common types such as integral box girder,U-shaped beam and small box girder.Choosing a suitable beam type should not only consider the economy and aesthetics,but also consider whether the force is reasonable.Based on the first phase project of Changsha-Zhuzhou-Xiangtan West Ring Line(South Extension Line of Changsha Rail Transit Line 3),this paper analyzes the structural form of simply supported beam and optimizes its stiffness and deformation,which can provide reference for the subsequent design of simply supported beam.
