摘要: 针对2009年9月3日下午重庆市高家花园大桥右幅桥跨中区段在箱梁内维修加固时发生意外火灾,以温度 场数值模拟的基本理论为依据,采用ABAQUS有限元软件对该箱梁进行变截面有限元实体建模,与实际监测数据 进行参照性对比,计算所得的挠度值与实测值基本相符,对桥梁结构状况评估具有参考价值。

Abstract: On September 3,2009,the box girder of Gaojia Garden Bridge caught a fire during the maintenance and rein- forcement. Based on the theory and algorithm of Heat Transfer , the model of Gaojia Garden Bridge box girder with varying section has been established by use of the Finite Element Method and ABAQUS finite element software.The resuits got bv the model are compared with those got in the monitoring.The comparison shows that the calculated deflection values basica1- ly match the measured ones,which has a referential value for the evaluation on bridge structures condittion

Key words: box girder, Gaojia Garden Bridge, fire simulation, ABAQUS, finite element method analysis
