摘要
以绥芬河转体施工斜拉桥为背景,以控制截面的挠度和弯矩变化值为评价指标,利用有限元分析程序—桥梁博士3.0进行计算,对包括梁段自重、混凝土收缩徐变在内的多个结构参数进行了敏感性分析,最终得出对该桥线形和内力变化有显著性影响的敏感性参数,并据此提出了监控意见。
Backgrounded by the Suifen River Cable-Stayed Bridge constructed by swivel erection and taking the changing values of deflection and bending moment of controlled sections of the type of the bridge as the appraisal indices, this paper makes the calculation and sensitivity analysis of various structural parameters of the bridge, including dead weight of girder segment, shrinkage and creep of concrete, by means of the finite element analysis program Dr. Bridge 3.0, obtains the sensitivity parameters that have significant influences on the geometry and internal forces of the bridge and also puts forward corresponding suggestions for the construction monitoring and control in accordance with the calculation and analysis.
