| Abstract: | For the geometric control of long-span prestressed concrete continuous bridge,the observation method of the elevation,temperature and stress are introduced based on the construction of Tangbei bridge.The finite element model of the bridge is established using ANSYS and MIDAS software,by which the calculation result and the measured result are compared.The results indicate that they are equivalent,which provide valuable reference for the similar engineering. |
