Construction of Suspension Bridges across the Yangtze River in Jiangsu, China

摘要

As Jiangsu is located in the middle and lower reaches of Yangtze River with particular natural conditions and high navigational clearance requirements, suspension bridges are always one of the preferable bridge types to consider for crossings of the Yangtze. This paper gives a brief description of bridge type and main structural details about two completed bridges-the Jiangyin Bridge and the Runyang Bridge-and two bridges under construction-the Taizhou Bridge and the Nanjing 4th Bridge. This paper also gives a brief introduction to the design concept and methodology adopted for construction of river-crossing suspension bridges in Jiangsu and development and progress with regard to choice of main structural system.
