景区人行悬索桥的人行舒适度分析

Analysis of Pedestrian Comfort of Pedestrian Suspension Bridge in Scenic Spot

悬索桥由于其造型优美、结构受力明确、跨越能力突出,所以在景区尤其是山地型景区的应用较为广泛。但是,国内规范关于人行悬索桥的人行舒适性的评价较为空缺。以宜昌G348三峡公路天柱山人行悬索桥为例,结合大型有限元分析软件,参照《德国人行天桥设计指南(EN03)》的人行舒适性评价体系,详细介绍人行舒适性评价的过程,并对此类桥梁的振动控制设计从桥梁运营管理上提出新的解决思路。希望该思路为类似桥梁的人行舒适性设计提供参考。

Suspension bridge is widely used in scenic spots,especially in mountainous scenic spots,because of its beautiful shape,clear structural stress&outstanding spanning capacity.However,the evaluation of pedestrian comfort of pedestrian suspension bridge in domestic specifications is relatively vacant.Taking Tianzhu Mountain pedestrian suspension bridge of Yichang G348 Three Gorges Highway as an example,combined with large-scale finite element analysis software,and referring to the pedestrian comfort evaluation system in German Overpass Design Guide(EN03),it introduces the process of pedestrian comfort evaluation in detail,and puts forward a new solution for the vibration control design of this kind of bridge from the perspective of bridge operation management.It is hoped that this idea can provide reference for the pedestrian comfort design of similar bridges.
