摘　　要：系杆拱桥因造型美观、结构适应性强,在城市轨道交通桥梁中日益增多,但目前仍未有针对系杆拱桥的试验规范,若直接参考铁路规范中相关规定作为城市轨道交通系杆拱桥的评价指标限值,并不合理。为确定合适的评价指标限值,对国内外相关的评价指标研究进行调研,从桥梁横向刚度、竖向刚度、行车安全与舒适度三个方面对评价指标体系展开论述,对可能存在的问题进行探讨,并给出城市轨道交通系杆拱桥试验评价指标的建议取值,为今后我国城市轨道交通系杆拱桥的试验评价工作提供参考。Due to the beautiful shape and strong structural adaptability,Tied-arch bridges are increasingly being used in urban rail transit,but there is still no specific test for bollard arch bridges,and it is not reasonable to refer to the relevant provisions in the railway specification as the limit value of evaluation indexes for bollard arch bridges in urban rail transit.To determine appropriate evaluation indicator limits,this paper investigates the related evaluation indicators at home and abroad,discusses the evaluation indicators from the three aspects:lateral stiffness,vertical stiffness,and running safety and comfort,explores the possible problems,and proposes recommended values for the test evaluation indicators of urban rail transit tied-arch bridges.This provides a reference for future test evaluation work on tied-arch bridges in China's urban rail transit systems.
