| Abstract: | The stay cable is the main stressed structure of a cable-stayed bridge. Due to stress, fatigue and mental corrosions, it is easily damaged by the corrosions. In order to guarantee the safety of cable-stayed bridge, the service life of stay cable must be prolonged. According to the problems of the actual use of stay cable structures, effectiveness of new technology and technique to prolong the service life of the stay cable is researched and discussed. |
