密肋式T梁在城市中小跨径桥梁设计中的应用

Application of close-packing T-beam in small and medium span urban bridges

在城市中小跨径桥梁上采用密肋式T梁可以避免常规装配式空心板梁的一些先天缺陷,减少桥梁上部结构的长期病害。而且施工简单,安装方便,易于快速化施工,在城市桥梁设计中非常具有推广价值。通过对密肋式T梁内力分析计算和结构设计优化,为密肋式T梁在城市桥梁中应用提供借鉴。

The application of close-packing T-beam in urban small and medium span bridges can avoid some congenital defects of conventional fabricated hollow slab beams and reduce the long-term diseases of bridge superstructure.And the construction is simple,easy to install,easy to rapid construction and in the urban bridge design is very valuable.In this paper,through the internal force analysis and structural design optimization of close-packing T-beam,it provides reference for the application of close-packing T-beam in urban bridges.
