摘要
火山新区汾河景观桥为下承式连续梁拱组合体系桥,跨径布置为(28+36+80+36+28) m,桥面标准宽度为27 m,采用Midas Civil软件建立有限元计算模型,对该桥进行了静力分析、稳定性分析及抗震分析,根据计算结果得知,全桥各主要构件受力良好,桥梁整体线形控制较好。该桥的设计兼顾桥梁美学与工程经济性的要求,计算结果已为该桥的设计复核提供了参考。
The Fenhe landscape bridge is continuous through type spatial girder and arch combination bridge. The span arrangement is( 28 + 36 + 80 + 36 + 28) m,and standard width of the bridge is 27 m. Software Midas/Civil is used to establish a model of the bridge,and static analysis,seismic analysis and stability analysis are all considered for the model calculation. Calculating results indicate that main components of the full bride are all in compressed state under three working conditions. At the same time,holistic line type of the bridge is controlled well. Bridge aesthetics and engineering economics are both considered in design of the bridge. Calculating results in this text have offered reference for design review of the bridge.
