Study on measurement and simulation of noise field between long tunnel and underground interchange

This paper analyzes the traffic noise characteristics of the long tunnel and underground interchange based on field monitoring and investigation of traffic noise and frequency in the area where they are located. Numerical simulation methods were used to study the noise characteristics of the long tunnel and underground interchange, and a finite element model of the noise in the long tunnel and underground interchange was established. The results showed that the simulated noise field model effectively reflected the actual noise level. This lays the foundation for future research on traffic noise reduction methods for the long tunnel and underground interchange based on this model. The research results of this project can provide theoretical and technical support for the prevention of similar engineering traffic noise and the promotion and application of related technologies.
