超高性能混凝土在人行天桥上的应用分析

Application Analysis of Ultra-high Performance Concrete on Pedestrian Bridge

超高性能混凝土作为一种新型材料在人行天桥上应用日益广泛。为了提高超高性能混凝土人行天桥建造速度、规范装配式施工流程,结合我国常规人行天桥结构和居民出行需求,根据有限元计算结果和工程实例,总结出四种超高性能混凝土人行天桥结构型式,可满足装配式预制施工和快速建造需求,给超高性能混凝土人行天桥设计建造提供一定参考。

As a new type of material,Ultra-high Performance Concrete is increasingly used in pedestrian bridges.In order to increase the construction rate of Ultra-high Performance Concrete pedestrian bridges and standardize the assembly construction process,in combination with conventional pedestrian bridge structures and residents’travel needs in China,according to the results of finite element calculation and engineering cases,four types of Ultra-high Performance Concrete pedestrian bridge structures are summarized,which can meet the requirements of prefabricated construction and rapid construction,and provide some references for the design and construction of Ultra-high Performance Concrete pedestrian bridges.
