预应力混凝土盖梁设计

随着城市桥梁的发展,大悬臂盖梁桥墩越来越多。结合上海市北横通道天目路立交改建涉铁段工程,根据施工现场实际条件所限,将普通混凝土盖梁柱式墩改为预应力混凝土盖梁柱式墩,采用有限元软件MIDAS分析计算,可为同类型的工程提供借鉴。

Design of Pre-stressed Concrete Bent Cap

With the development of urban bridge,there are more and more long-cantilever bent cap piers.Combined with Shanghai North Cross Channel Tianmu Road Interchange Reconstruction Involved Railway Section Project,based on the practical condition limited of construction field,the normal concrete bent capcolumn pier is replaced by the pre-stressed concrete bent cap column pier.The finite element software MIDAS is used for analysis and calculation,which can be referred for the similar projects.
