摘要
南京长江第四大桥为主跨1418m的双塔3跨悬索桥,其主缆采用新型锚固钢板式锚固系统。主缆索股采用预制平行索股(PPWS)法架设,除设置通长索股外,在南北边跨各增设若干背索。文章系统介绍了南京四桥主缆索股架设关键技术,可供后续类似工程参考。
The 4th Yangtze River Bridge in Nanjing is a three-span suspension bridge with double tower which main span is 14IBm,the main cable using a new type anchorage system with anchored steel plate and is erected by prefabricated parallel wire strands （PPWS）,besides the continuous cable strands, some backstay cables are added at the south and north side spans respectively. This paper introduces the key technologies of main cable erection of the Fourth Nanjing Yangtze River Bridge systematically, which are available for similar projects.
