摘要
近年来,人行悬索桥以其外观新颖、线形优美和投资回报高等优点在旅游景区得到广泛应用.但在项目快速建设的同时,目前仍缺少相应的研究成果来指导设计.以某典型人行悬索桥合理成桥状态为基础,分别选取主缆垂跨比、抗风缆倾角、抗风缆矢跨比、抗风缆初始预应力和空间主缆倾角5项参数,进行静动力特性研究.总结了上述设计参数对人行悬索桥静动力特性的影响规律,给出了景区人行悬索桥设计参数的合理取值范围,可为今后景区人行悬索桥的设计提供参考.
Abstract
In recent years,pedestrian suspension bridge has been widely used in scenic spots for its novel appearance,beautiful line shape and high return on investment.However,with rapid construction of such projects,there is still a lack of relevant research to guide the design.In this paper,a typical pedestrian suspension bridge in a scenic spot is taken as an example,and five parameters have been chosen to study static and dynamic characteristics of the bridge based on its reasonable completed state.The parameters include the vertical span ratio of the main cable,the inclination angle of wind resistant cable,the rise span ratio of wind resistant cable,the initial prestress of wind resistant cable and the inclination angle of spatial main cable.The influences of the above design parameters on the static and dynamic characteristics of pedestrian suspension bridge are summarized.At the same time,a reasonable range of design parameters is given,which can provide reference for future design of pedestrian suspension bridges.
