Taking Xiangjiang bridge on changzhutan intercity railway as an engineering background, which is 12 span bridge with rigid frame - combined continuous beam in cantilever pouring construction, the finite element model was constructed respectively. 5 conventional closure options and 3 system transformation orders were simu- lated to calculate the vertical displacement and stress of the bridge. The stress and deformation were discussed under different closure orders and system transformation orders on the general rules for such similar bridge were discussed. The results show that plan 1,2or5 clos...
