中承式钢拱桥静力参数的敏感性分析
Sensitivity analysis of static parameters of a centre-supported steel arch bridge
摘要
Abstract
This paper is an effort to investigate the influence of different static parameters on the con-struction process of the medium-supporting steel arch bridge,and to improve the construction accuracy of the medium-supporting steel arch bridge.By taking a medium-supporting steel arch bridge as the research object,the study includes establishing a simulation model of the whole bridge by adopting the finite ele-ment analysis software Midas Civil,and investigating the influence of the change of structural capacity,e-lasticity modulus,shrinkage and creep,the overall temperature rise and fall,and construction cable force on the deflection and stress of the bridge from various factors affecting the bridge alignment and internal force.The results show that the deck slab capacity and construction cableway force,which have signifi-cant influence on the bridge cableway force,mid-span box girder deflection and stress,need to be con-trolled as sensitive parameters during the construction process;and the modulus of elasticity,shrinkage creep,and the overall temperature rise and fall,which have less influence on the bridge cableway force,mid-span box girder deflection and stress,need to be controlled as non-sensitive parameters during the construction process.关键词
