Considered the difference of creep mode between the core concrete filled in steel tubes and common concrete, three modds was used to calculate the creep deforming of a box-handle CFST arch bridge, which detached （section） model and combined （section）model separately, Draned the following conclusions, the calculation results of the separated model is highly close to the calculation results of combination model, these models have enough precision when applied to construction monitoring; the cross creep deforming of Beimen bridge is small, so ...
