摘要: 目前对施工过程中静风荷载对钢管砼拱桥整体稳定性的研究还不多,通过一个工程实例在这方面做了一些研 究.通过有限元分析,结果证明风速越大,整体稳定安全系数越低;风荷载较小时对稳定性影响不明显,当风速超过 一个定值以后,影响效果非常明显.风荷载作用下,同时考虑材料非线性以后,荷载稳定安全系数降低较大;风荷载 作用下,考虑双重非线性比考虑材料非线性的稳定安全系数有所降低,但是降低幅度不大.

Abstract: There is little research on the wind-induced lateral torsional buckling stability problem for long-span concrete filled steel tube arch bridge.Through a practical bridge,the stability of CFST arch bridge sufered wind load was analyzed.The resuits show that the stronger the wind rapidity is,the smaler the coeficients of stability is,and weak wind have little influence on the stability,but the strong wind afects greatly on the stability of the structure,and the nonlinear considered under the analysis of stability of CFST arch bridge in construction is better,and the material nonlinear has a greater influences on the stability of the bridge than the geometrical nonlinear does.

Key words: CFST arched bridge, construction, stability, wind load
