项目名称拉吊索结构耐久构造与可检修易更换技术的研究获奖等级二等奖斜拉桥、中下承式拱桥因造型美观、跨越能力强、造价经济,在国内外广泛应用,但其拉吊索检查困难,现有的各种无损检测方法不能全面显示拉吊索病害,出现了多起拉吊索突然断裂、甚至桥梁坍塌的严重事故。拉吊索结构耐久构造与可检修易更换技术的研究,就是针对桥梁拉吊索耐久.陛难题,经过6年的刻苦攻关,在拉吊索设计、制造、施工、检修、损伤判定等 Project Name Stretchable structure of sling structure and easy to replace replaceable technology Research Award Second prize of cable-stayed bridge, middle and lower berth Due to its beautiful appearance, strong ability of crossing and economy, it is widely used both at home and abroad. However, Slings inspection difficulties, the existing non-destructive testing methods can not fully display the sling disease, there have been a number of pull slings suddenly broken, and even the collapse of the bridge serious accident. The research on the durable structure of the sling structure and the replaceable technology that can be repaired and repaired is aiming at the durability of the sling of the bridge. After six years of painstaking research, the design, manufacture, construction, overhaul and damage judgment of the sling
