| Abstract: | With the tubes and anchoring devices and horn mouth friction loss tests for 32-m post-stressed concrete box beams of the Wu-Guang Passengers-oriented Special Railway as practical examples, the prin ciple of the friction test is introduced in the paper, from which the calculation method of the friction coefficient μ and the deviation coefficient k are derived by the dualistic linear regression method, the effects of which on the pre-stressing stretch are discussed. It is proved in practice that the friction coefficient calculation method is reasonable and easy to use, and the obtained parameters may serve as technical grounds for the construction of prefabricated box beams. |
