| Abstract: | Sanhegou Bridge in Xuanen County is a new structure of pre-stressed sunflower-shaped arch bridge.The article introduces its structural characteristics and design,and analyzes its stress performance by the finite element program.The calculation result shows that Sanhegou Bridge in Xuanen County can satisfy the requirements of strength,deflection and so on under the design load,which has a certain reference for the design of the same bridges in China. |
