| Abstract: | In view of the characteristics of curved beam bridge, the article deeply analyzes its aspects, and demonstrates the simulating method of prestressed curved beam bridge to give the correct simulating method. Combined with the new standard, the article fully analyzes the method to enhance the concrete grade and gives the optimal scheme. The final conclusion is given. The article sums up some cautions for the design in three aspects of the superstructure design, support design and structural calculation. |
