| Abstract: | 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. |
