| Abstract: | Combined with an actual project Guangxi Chongzuo to Jingxi highway-GuLongShan bridge, using spatial finite element software MIDAS/CIVIL to calculation and analysis the structure in construction of cantilever and completion stage beam＇ s displacement and stress. The study may provide some references for linear and stress control during cantilever construction of box girder. |
