Research on Construction Technology of Inclined Pylon of Single Pylon Cable-Stayed Bridge without Backstays
A new type of cable-stayed bridge, single pylon cable-stayed bridge without backstays is used in the Zhenshui Road Bridge in Xinmi City, China’s Henan Province, which adopts PC box girder with corrugated steel webs. It has many advantages such as light girder deadweight, low pylon height and avoiding webs longitudinal cracks. This novel bridge is adopted firstly in China. Cast-in-place method with bracket is used in the construction of the bridge’s inclined pylon because of its complex construction technology and tight construction period. In this paper, interests are focus on the scheme comparison and selection of bracket construction, the establishment of bracket’s computational model and the result of numeric analysis etc. The chief aim of this investigation was provides useful reference and enlightenment to similar bridge types.
