Abstract

Hongdu Bridge is the fifth large bridge crossing Gan River in Nanchang urban centre,with the total length of 9.5 km,consisting of south and north main bridges,south-north connection and Yangzizhou Viaduct,etc.The south main bridge,the main channel bridge is designed as a self-anchored suspension bridge with twin towers and single cable plane with the main span of 195 m.Then,the designs and structure performance analyses of main beam,main tower,basis and cables system are pointed out and the incremental launching method is introduced.Hongdu Bridge has been completed officially for service since March,2009.
