Abstract：Abstract：Research purposes： With the implementation of medium and long-term railway network planning and the rapid development of China's high-speed railway, the noise problem is increasingly arousing great public concern. The exceeding of ambient noise functional zone on both sides of the railway has become a common problem, and parts of railway projects have not yet passed the environmental acceptance check due to the noise problem. In order to normalize and unify noise control target and noise control measure choice in environmental impact assessment and design, in order to solve the problem of noise control in the environmental acceptance check projects, it is necessary to carry out the research on the principle and measures of railway noise management and the application of the conditions. Research conclusions： (1)Railway noise control should give priority to take engineering measures on the noise source and acoustic pathways and implement the active control of noise, at least to ensure a reasonable indoor acoustic environment quality. (2)Train noise sources are mainly concentrated in wheel and rail area under the body more than 2.0 meters, barrier above the rail height 2.05 m can effectively shield direct sound from the wheel and rail area and the lower part of the body area. (3)In the sound barrier design, the sound barrier protection range, height, length should be based on the characteristics of the railway source, combined with sensitive point noise reduction requirements, terrain, geomorphology and other working conditions, to adopt different design parameters. (4)The research results can provide reference for the prevention and control of railway noise.
