越南富美桥为一座(162.5+380+162.5)m的混凝土斜拉桥,主梁为现浇钢筋混凝土π形梁,梁高较小(2.001～2.305m),索距较大(10m),横梁和梁上拉索锚头预制,边主梁和桥面板现浇,主梁与锚墩固结。采用1套挂篮进行主梁施工,建造工期约30个月。介绍该桥设计及审查所采用的规范、斜拉桥的结构布置及审查过程中的计算分析和验算细节,包括:有限元模型及整体分析,非线性施工过程分析,地震反应分析,船撞分析,拉索破坏、疲劳及换索分析,空气动力分析,活载效应以及环境因素。
Vietnam Fulmy Bridge is a (162.5 + 380 + 162.5) m concrete cable-stayed bridge, the main girder is a cast-in-place reinforced concrete π-shaped beam with a small beam height of 2.001 ~ 2.305m and a large cable distance of 10m. And the beam on the anchor head precast, while the main girder and the bridge deck in situ, the main beam and anchorage consolidation. The use of a set of hanging basket girder construction, construction period of about 30 months. Describe the specifications used in the design and review of the bridge, the structural layout of the cable-stayed bridge and the computational analysis and checking details in the review process, including: finite element model and overall analysis, nonlinear construction process analysis, seismic response analysis, ship collision analysis , Cable damage, fatigue and change analysis, aerodynamic analysis, live load effects and environmental factors.
