摘要
由于斜拉-悬吊协作体系桥梁索结构的锈蚀、断裂等病害会严重影响桥梁结构的安全性和耐久性,通过对乌江大桥拉索更换工程的跟踪,重点探索和研究了斜拉-悬吊体系桥梁拉索更换的相关技术要领和监控方法,为斜拉-悬吊协作体系桥梁拉索或吊索的正确、及时更换,以及该桥型的设计和加固维修提供参考依据。
Cable-stayed-suspension bridge mainly depends on the stay cables and the suspension cables to bear the load together,while the corrosion and fracture of the cables will seriously affect the safety and durability of the bridge structure.Correct and timely replacement of the cables is the most effective way to solve the problem.By tracking the cable replacement of Wujiang River Bridge,the technology essentials and monitoring method for the cable replacement of cablestayed-suspension bridge were explored.The results provide reference for the design and reinforcement maintenance of similar bridges.
