大跨度桥梁成桥状态下安全分析模型研究

Study on the safety analysis model of long span bridge under bridge conditions

以某大跨度斜拉桥梁施工过程中安全评估为主线,围绕施工中的主梁、主塔结构内力等方面,结合有限元软件针对某工程实例施工过程中成桥分析模型和施工状态荷载组合效应分析进行研究,阐述了通过成桥状态下斜拉索索力对主梁和索塔应力安全评估影响的研究。

Based on a large span cable-stayed bridge construction process safety evaluation as the main line,and around the internal force of the main girder and the main tower structure and other aspects, it is combined with the finite element software to study the combination effect of the analysis model and the construction load. It elaborates the safety assessment of the bridge cable force on the beam and tower stress.
