| Abstract: | Combining with the engineering examples,the paper introduces the linear supervision and the stress inspection of the beam in the hanging basket cantilever casting of the large-span prestressed concrete continuous beam,adopts the methods of the numerical simulation,undertakes the finite element simulation analysis of all the construction stages,compares with the observation data,and proves that the supervision result meet the demand of the regulation. |
