Abstract
Railway noise has become an important factor restricting the further development of railway and endangering human health. Because of the particularity of the structure of the railway bridge, the noise radiation source is strong, the noise varies with the distance and the noise reduction effect of the sound barrier is different from that of the railway section. Therefore, how to effectively control the impact of railway noise on residents on both sides of the bridge section has become the focus of environmental protection workers, research the influence of noise of railway bridge segment noise in residential area along the railway is very important. In the acoustic test program of high-speed railway u-shaped beam, we will select the most appropriate noise reduction scheme through the computer simulation and model test of HSR u-shaped beam with different structural forms of test, and provide reliable reference for practical engineering.
