Construction Technology of Single Tower Self-anchored Suspension Bridge of Guangzhou Liede Bridge

As a single tower self-anchored suspension bridge,the main bridge of Guanghzou Liede Bridge has a spatial cable system and asymmetrical main side span,which have made the bridge having high level technologies and construction difficulty. In this paper,the construction technology and implementation effect of its shellshaped irregular cable tower,incremental launching method of box girders with maximum 60m various spans and spatial three dimensional cable system have been introduced,so as to provide references for similar bridge construction.
