| Abstract: | Of the Dong Shaoxi extra-long bridge on Xuan-Hang railway, the main bridge is of a 112m steel tubular concrete basket-handle tied arch bridge to the Nilsson system. The arch ribs are made into the shape of fold lines rather than circular curve lines. Half a span of it is pre-fabricated spatially in shop and the whole is vertically fabricated in segments on site where cable cranes are used for lifting operation and the segmental cantilevered assembling method is employed with tower cranes fulfilhng the work of diagonal tensioning, fastening and suspension necessary to complete the erection of the arch bridge. |
