钢箱梁具有拼装快、自重轻、跨度大等特点,在公路桥梁工程中越来越受到重视。本文结合常溧高速C匝道跨扬溧高速钢箱梁施工实例,探讨了跨越高速公路钢箱梁施工的关键技术,从架设方案、钢箱梁加工、交通组织和高速公路安全防护等方面进行了论述,为今后类似桥梁的架设施工提供参考。
Steel box girder has assembled quickly, light weight, span and other characteristics, more and more attention in highway bridge engineering. In this paper, the key technology of steel box girder spanning expressway is discussed based on the construction example of Changjiang High-speed C-ramp across Yangli Steel High-speed Steel Box Girder. The key technologies of steel box girder construction across expressway are discussed, including erection plan, steel box girder processing, traffic organization and highway safety protection Discussion, provide reference for the similar bridge erection construction in the future.
