Attenuation Analysis of Novel Metamaterial Vibration Isolation Wall in Subway Engineering

Key Points

• The metamaterial wall significantly reduces vibration transmission, enhancing structural integrity in subway systems.
• In field tests, the vibration level was reduced by 30%, demonstrating a notable attenuation effect for passenger comfort.
• Observational analysis using real-world subway scenarios revealed critical performance aspects of the metamaterial wall.
• Supports the adoption of advanced materials in engineering, but further study is needed to generalize findings.
