摘　　要：兼顾轻盈、通透、简洁明快的景观要求,同时满足跨径较大、梁高较小、平曲线半径较小、处于高地震区,以及地质条件较差等诸多限制条件,在景观人行桥的设计中采用钢管桁架结构(部分构件采用钢管混凝土加强)。通过对某公园内一座管桁式人行桥的设计,给出了合理的结论,并进行了部分参数的敏感性分析,希望为今后同类型景观桥梁的设计提供参考。Considering the landscape requirements of lightness,transparency,conciseness and vividness,also meeting the numerous limiting conditions of larger span,lower beam height,smaller horizontal radius,locating at high earthquake region and poor geology,the steel-tube truss structure(concrete filled steel tube to reinforce the partial structures)is used in the design of landscape footbridge.The reasonable conclusion is given through the design of a steel-tube truss footbridge in a park.And the sensitivity analysis on the partial parameters is carried out,which hopes to provide the reference for the design of the similar landscape bridges in the future.
