| Abstract: | 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. |
