摘要
为解决传统预制T梁在桥梁智能化建造中面临的横隔板数量过多、模板安拆困难及智慧化程度低等问题,该文围绕横隔板道数优化和装配式横隔板的应用两个方面展开研究.通过对不同横隔板配置方案的分析,以及对装配式横隔板与预制横隔板在桥梁横向刚度贡献上的对比,深入探究了横隔板对桥梁性能的影响.研究结果表明:T梁少横隔板体系在智能化建造中是可行的,但无横隔板体系对桥面板的性能提出了更高要求;装配式横隔板相较于预制横隔板,在桥梁横向刚度上的贡献较低,采用装配式横隔板会增大桥面板的受力;横隔板的安装位置对桥梁横向刚度具有显著影响.
Abstract
The traditional precast T-beam faces issues such as excessive diaphragms,difficult formwork installation and removal,and low levels of intelligence in intelligent bridge construction.To address these issues,this paper focused on the optimization of the number of diaphragms and the application of prefabricated diaphragms.By analyzing different diaphragm configuration schemes and comparing the contributions of prefabricated diaphragms and precast diaphragms to the lateral stiffness of the bridge,this paper deeply explored the impact of diaphragms on bridge performance.The research results indicate that the T-beam system with fewer diaphragms is feasible in intelligent construction,but the system without diaphragms places higher demands on the performance of bridge decks.Additionally,compared to precast diaphragms,prefabricated diaphragms contribute less to the lateral stiffness of the bridge,and their use increases the stress on bridge decks.Furthermore,the installation position of diaphragms has a significant impact on the lateral stiffness of the bridge.
