LONG-SPAN INCREMENTAL LAUNCHING CONSTRUCTION TECHNIQUE FOR OVERWEIGHT FLEXIBLE STEEL BEAM OF STEEL STRUCTURE BRIDGE

在桥梁工程顶推施工过程中,导梁施工是非常重要的辅助结构,应用顶推法施工原理及施工方法,以实际工程为例,对仿真模拟顶推过程进行分析,对钢结构桥梁大跨顶推施工技术进行讨论,有效降低主梁施工过程中产生的内力大小,进而保证施工质量和施工安全,节省施工成本。

Guide beam construction is a very important auxiliary structure during the incremental launching construction of bridge engineering. The paper expounded the construction principle and construction method of the incremental launching method. Taking the actual project as an example, the simulated incremental launching process was analyzed, and the longspan incremental launching construction technique of the steel structure bridge was discussed to effectively reduce the internal force generated during the main beam construction process, so as to ensure the construction quality and safety and save construction costs.
