| Abstract: | The structure characteristics and design idea of main beidge of Horseshoe Hill No.1 bridge were introduced.On that basis,the longitudinal mechanical calculation of the bridge and stability calculation of the piers were completed.The results show that crack resistance,compressive resistance and carrying capacity of the bridge girder crack section meet the requirements of China current code.The stability factor of the completionin stage under the live load is 19.6 which show that the bridge has higher stability. |
| Keywords: | continuous rigid frame construct design high pier structure calculation |
