Abstract：
The paper investigates the prestressed friction coefficient test of concrete continuous rigid frame bridge The prestressed friction coefficient values were obtained with the principle of least squares, and were compared with the design value and the specification value. The results show that experimental value larger than both of them. Materials and construction of prestressed bellows accounted for the major. In order to minimize the friction in construction, thereby reducing the loss of prestress, the author with actual construction experience advised relevant recommendations of prestressed bellows in material requirements, locating and installation, connection, penetrate the core pipe, process checks.
