异型系杆拱桥关键设计参数分析

摘要:

以某座位于城市核心区的异型系杆拱桥为例,对该桥的矢跨比、主拱刚度、纵、横梁布置形式等参数进行设计分析,研究了该类型系杆拱桥的受力机制和设计特点,明确了该类型桥梁关键设计参数的取值原则,可为同类型桥梁结构体系设计提供参考。

Abstract:

Taking a special-shaped tied-arch bridge located in the core area of the city as an example, the influence analysis of the bridge’s rise-span ratio, main arch stiffness, longitudinal and transverse beam layout and other parameters are carried out, and the force mechanism and design feature of this tied-arch bridge are studied. Therefore,the value principle of the key design parameters of this type of bridge is clarified, which can provide a reference for the design of the same type of bridge structure.
