In the acoustic test program of high-speed railway channel girder, the most appropriate noise reduction scheme was selected by computer simulation and model test of HSR channel girder with different structural forms to be reliable reference for practical engineering. This report is focused on the scale model test part.In the scale model test, scale of scale model of HSR channel girder was selected by theoretical analysis at first. Secondly, in the formal test, the influence of the change of HSR channel girder angle on the noise reduction was verified. In addition, it can be seen from the test results that the noise reduction of HSR channel girder is related to the train running speed, and the noise reduction effect is better than 340km/h when the speed is 300km/h.", }
