| Abstract: | Combined with the actual engineering case of a prestressed continuous girder bridge in Shanghai-Nanjing Intercity High-speed Railway,the article used the finite element analysis software,analyzed the impact of the elastic modulus of concrete,bulk density of concrete,prestress,temperature,concrete shrinkage creep and other factors on the linear control of the main beam in this bridge,and proposed the appropriate control measures. |
