摘要
斜拉索是斜拉桥的主要受力结构。由于应力腐蚀、疲劳腐蚀和金属腐蚀,斜拉索容易损坏失效。为了保证斜拉桥安全营运,需要延长斜拉索的安全使用寿命。针对斜拉索结构的实际应用问题,研究和探讨延长斜拉索安全使用寿命的工艺技术问题。
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.
