摘要
吊杆作为连接拱桥桥面和拱肋的重要构件,其工作性能的好坏直接关系到拱桥运营的安全。文章以江苏省某高速公路的一座吊杆拱桥为例,详细描述了该桥定期检查中吊杆存在的问题,并对吊杆的病害成因进行了分析。通过该桥吊杆取样钢丝的室内静力拉伸试验结果,对该桥吊杆钢丝的力学性能进行了分析。文章对在役拱桥吊杆的检测及力学性能的研究具有一定的借鉴意义。
Suspenders connecting the deck of arch bridge with its arch rib as a key components,and their workingconditions are related to the safety of bridge structure directly. Taking a suspender arch bridge of an expressway inJiangsu province as an example,this paper described the suspenders忆diseases which found in periodical inspection indetail and analyzed possible causes. Afterwards,with the static tensile experiments of sampled steel wires from thisbridge,the mechanical properties of its suspenders steel wires were analyzed. This paper has certain reference meaningsfor the inspection and mechanical research of arch bridge suspenders in service.
