| Abstract: | In view of the cracking problem in box girder,insufficient design method of concrete box girder in our country is analyzed, and method of control stress value selected about concrete box girder is discussed. Combined with specific engineering, the theoretic analysis by using finite element has been done in model of box girder during construction period, and the contrast has been performed between the theoretic stress results and the actual results in the monitoring points of the monitoring section. High quality of box girder is guaranteed and crack occurrence is effectively controlled. |
| Keywords: | crack of box girder design method control stress finite element analysis |
