下承式系杆拱桥稳定性影响参数研究

Influencing Parameters of Stability for Reinforced Concrete Tied-arch Bridge

基于拱桥稳定性分析理论,通过有限元分析软件ANSYS对天门市陆羽大桥的稳定性影响因素进行了分析,探讨了矢跨比、系梁抗弯刚度、拱肋抗弯刚度、吊杆刚度和横撑形式等参数对拱桥稳定性的影响。

Based on the stability theory of arch bridge,finite element analysis software ANSYS is used to study the influencing parameters to the stability of a reinforced concrete tied-arch bridge.Those parameters include the rise/span ratio,the bending rigidity of tie beam,the rigidity of rib,the rigidity of suspender,the forms of diaphragm.
