摘　　要：该文通过对系杆拱桥出现单根或两根吊杆突然失效的情形进行桥梁内力与变形状态的分析,评估失效事故发生时桥梁的安全性,提出桥梁紧急处治预案,为管养部门提供理论依据,便于其对桥梁运营状态进行科学合理的评估和养护。同时提出单根、多根,以及全桥吊杆更换的方案研究,分析吊杆更换对城市交通运营的影响,为远期更换桥梁吊杆提供前瞻性的意见。By analyzing the internal force and deformation status of the bowstring arch bridge when single or two suspenders have a sudden failure,the article evaluates the safety of bridge when the sudden failure acci-dent happens,and puts forward the emergent treatment plan so as to provide the theoretical basis for management departments and to facilitate an scientific and reasonable assessment and maintenance of bridge operation.Also the article puts forward the study on the replacement plans of single one,two or the whole bridge suspenders,and analyzed the impact of suspender replacement on urban traffic operations,which provides the forward-looking opinion for the long-term suspender replacement of the bridges.
