| Abstract: | Jiaxing Urban Expressway Ring Line Project crosses the olg ground bridge (Longfeng Bridge) of Beijing-Hangzhou Grand Canal. It is proposed to use the steel-UHPC composite girder scheme. Compared with conventional prestressed concrete continuous beams, corrugated steel web continuous beams and bowstring arch bridge schemes, the aspects of economy, construction scheme and durability are compared and analyzed. The results show that steel -UHPC composite beams have obvious advantages and good application prospects in long-span bridge projects. |
