Abstract: Wujiang Cable-stayed and Suspension Combination Bridge is a new type of bridge which combines cable-stayed bridge and suspension bridge together, and it is also the first bridge of this type in the world.To build the bridge, some new ideas were brought forth in the design of the bridge, and new materials and technology were abopted.The article has intruduced the construction method of using cable platform instead of cate-way, erecting 100 tons of box girder with cableway and cantilever assmblage, tensioning the stays of the cable-stayed bridge by different times.

Key words: cable-stayed and suspension combination bridge, construction method, building the main cable, erection with cableway and cantilever erection, tension by different times
