Installation Technology of Steel Box Girders in Shanghai Yangtze River Bridge
 
Abstract:Chongming river-crossing tunnel project in Shanghai is the longest compound project of tunnel and bridge at present, which is composed of south port tunnel project and north port bri
dge project. This paper introduces some new technologies of box girders installation implemented in Shanghai Yangtze River Bridge, including making full use of bridge crane by changing its hoisting methods to hoist the steel box girders with rather small equipments, temporary anchorage of No.0 segment on   tower column without lower  cross-beam, lifting and matching supper-wide steel box girders and constructing a insert-lift type temporary pier. By succes
sfully implementing the mentioned technologies, Shanghai Yangtze River Bridge is rapidly completed with high quality and low cost.
