以洛河特大桥建设项目为依托,对高墩大跨连续刚构桥的关键施工技术开展系统研究.在项目建设中,运用了大体积混凝土温控、空心墩快速封顶、高墩边跨现浇段不配重等施工技术,相关技术成果可为同类高墩大跨连续刚构桥的施工提供借鉴.
Study on Key Construction Techniques for the Main Bridge of Luohe Super Major Bridge
Based on the project of Luohe Super Major Bridge,a systematic study is conducted on the key construction tech-niques of high pier and long-span continuous rigid frame bridge.During the construction process,the relevant technical a-chievements such as mass concrete temperature control,rapid capping of hollow pier,non counterweight construction of cast-in-situ section of high pier side span and so on can provide reference for the construction of similar high pier and long-span continuous rigid frame.
