Abstract:The main bridge of Yibin Zhongba Jinsha River Bridge is a 252m+175m single-tower double cable-stayed prestressed concrete cable-stayed bridge. This paper focuses on the general layout, structural characteristics, main calculations and scientific research tests of this bridge.

Abstract:In recent years, with the improvement of the cultural living standard of urban and rural residents in China, a large number of large-scale UE comprehensive recreational facilities have been constructed in various places, and the prestressing technology, with its unique advantages, plays an increasingly important role in it. This paper will combine with the Suzhou Sports Center Stadium Project, focusing on the structural characteristics and construction technical requirements of prestressed concrete inclined beams, which includes prestressing aperture steel pipe stay managed, prestressing oblique tensioning operation process, aperture reverse grouting process, etc.

Abstract:This paper takes Dali - Baoshan highway K422 +665 bridge prestressing project as an example, introduces the process and construction technology of typical in vivo prestressing construction.

Abstract:Traction is another engineering application method different from jacking, turning and lifting. This paper briefly introduces a pipeline cross-sea laying project traction construction program design.
