| 摘要：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略论和验算细节,包括:有限元模型及整体略论,非线性施工过程略论,地震反应略论,船撞略论,拉索破坏、疲劳及换索略论,空气动力略论,活载效应以及环境因素。 Abstract：Vietnam beauty rich bridge as a 162.5/380/162.5) m concrete cable stayed bridge, girder cast-in-place reinforced concrete PI shaped beam, the beam height is small (200.1 to 2.305m), cable distance is larger (10m), beam and beam cable anchor head prefabricate, edge main girder and bridge panel cast-in-place, girder and anchor pier consolidation. Using 1 sets of hanging basket girder construction, the construction period of about 30 months. Introduced in the bridge design and review the specification, cable-stayed bridge and the structure arrangement and the review process calculation and analysis and calculation details, including: finite element model and the overall analysis, the construction process of the nonlinear analysis, seismic response analysis, analysis of vessel collision, cable damage and fatigue and analysis of cable replacement, aerodynamic analysis, live load effect and environmental factors. 引言：1前言越南富美桥为一座全混凝土斜拉桥,是越南胡志明市西贡河上连接D2区与D7区的重要工程。斜拉桥主桥长705m,主跨380m(见图1)。D2区侧高架引桥长约638m,D7区侧高架引桥长758m。该桥属于越南政府,工程总造价为1.05亿美元,采用基于私有资金的设计建造及BOT模式建设,投资业主为 ，越南语论文，越语论文范文 |
