| Abstract: | Youxi Bridge Main Bridge in Xiang-pu Railway is a 1×140 m with deck rigid-frame reinforced concrete box arches.It adopted the construction scheme of assembling military beam arch centers with the cable-stayed clasping and hanging method,and assembling main bridge’s rigid frames above in replacement of the cable crane.This paper introduces the design of the military beam arch centers and the assembling of the cable-stayed clasping and hanging system and the linear control of construction in details.Assembling military beam arch centers with such long spans is uncommon in China,which can be guidance to similar projects. |
