摘要
某系杆拱桥经过多年运营,吊杆的防腐层出现老化损坏,吊杆钢束和锚头严重锈蚀需要更换,但受原设计构造制约,不具备更换新吊杆条件,故研究在旧吊杆前后各增加一根新吊杆替代旧吊杆的方法,并提出相应技术建议,为处理类似工程问题提供借鉴。
After many years of operation, the antisepsis coating of suspenders becoming aging damage leads to serious corrosion of suspender steel bunch and anchor head, a tied arch bridge must change old suspenders. But by the restriction of the original design, conditions do not permit to change old suspender. So this paper resear-ches the methods of adding one new suspender before and after one old suspender respectively to replace old one, and makes appropriate technical advice to give reference for the similar problem of projects.
