无推力斜靠式拱桥设计参数研究

Study on Design Parameters of the Leaning-type Arch Bridges Without Thrust

以昆山市玉峰大桥为工程背景,对无推力斜靠式拱桥主要设计参数矢跨比、拱梁刚度、斜拱倾角、横撑数量、刚度及位置等进行研究,得出各参数对结构受力及稳定性的影响规律,为此类桥梁的设计提供参考依据。

With Kunshan Yufeng bridge as an example,the main parameters of the leaning-type arch bridges without thrust such as the ratio of rise to span,the stiffness ratio,the rake angle of leaning arch,the number,the stiffness and location of transverse bracings are investigated.The law that design parameters influence the structure internal force and stability can provide reference for the design of the leaning-type arch bridges.
