［摘要］随着我国经济的发展和桥梁建设水平的大幅提升，越来越多的旅游景区为提升服务效果开始修建人行玻璃悬索桥，人行玻璃悬索桥以其独特的造型和强大的跨越能力，在旅游观光建筑中得到了很好的发展。人行玻璃悬索桥加劲梁一般采用纵、横方钢焊接成梁格体系，上面铺设钢化玻璃，具有自重轻、梁体刚度小等特点。为保障后期运营桥梁的安全，以某景区一座跨径178m的玻璃悬索桥为背景，采用有限元分析软件，对桥梁结构的静力及动力指标进行分析和研究，并采用等效荷载加载的方式对桥梁的承载能力进行鉴定。结果表明桥梁结构承载力满足设计要求。

Abstract: With the development of China’s economy and the improvement of bridge construction level, more and more tourist attractions begin to build pedestrian glass suspension bridges in order to improve the service effect. With its unique shape and strong crossing ability, pedestrian glass suspension bridges have been well developed in tourism and sightseeing buildings. The stiffening beam of pedestrian glass suspension bridge is generally made of longitudinal and transverse steel welded into beam lattice system and laid with toughened glass, which has the characteristics of light dead weight and low beam stiffness. In order to ensure the safety of the bridge in later operation, taking a glass suspension bridge with a span of 178m in a scenic spot as the background, finite element analysis software was used to analyze and study the static and dynamic indicators of the bridge structure, and the bearing capacity of the bridge was evaluated by using equivalent load loading method. The results show that the bearing capacity of the bridge structure meets the design requirements.
