| Abstract: | Based on the engineering background of a new extradosed cable-stayed bridge with tower-beam synchronous construction,the finite element software is used to establish the local solid analysis model of the tower-beam-pier consolidation segment,and the synchronous construction process of the whole tower beam is simulated.The local stress distribution law of the tower-beam-pier consolidation segment in several important construction stages are analyzed and summarized.Therefore,the finite element calculation results are compared with the measured data to verify the accuracy of the calculation results and the test results. |

| Keywords: | simultaneous construction of tower beam pier-tower-girder fixed segment local stress solid finite element model |
