摘　　要：人行天桥的设计很少在石油化工工程设计中出现,对油气站场内人行天桥的设计缺少经验,对桥梁结构的一些影响因素与油气站场结构设计有所不同。文中针对桥梁结构设计的方法和特点,采用MIDAS/Civil桥梁有限元分析软件,对油气站场内人行天桥进行建模分析,分析温度变化对人行天桥结构的影响,结果表明,温度对钢结构人行桥梁的影响很大,不容忽视。The design of pedestrian bridges is rarely seen in petrochemical engineering design.There is a lack of experience in the design of pedestrian bridges in the oil and gas station,and some influencing factors of the bridge structure are different from the structural design of the oil and gas station.Based on the methods and characteristics of bridge structural design,MIDAS/Civil bridge finite element analysis software is adopted in this paper to conduct modeling of the pedestrian bridges in the oil and gas station,and analyze the influence of temperature change on the pedestrian bridges structure.The results show that temperature has a great influence on steel structure pedestrian bridges,andcannot be ignored.
