| Abstract: | The accurate estimate of the post tensioned prestressed concrete continuous beam bridge prestress loss is an important guarantee to prevent beam body from deflection and cracking. Channel friction test is an effective method of making the effective prestress to meet the design requirements. With the help of specific project practice, the principles, methods, points for attention and results analysis of the channel friction test will be elaborated. |
