This study addresses public complaints regarding vibration and noise disturbances along an operational metro line with short-sleeper monolithic trackbed. Field investigations and measurements were conducted at both the metro track and sensitive receptor locations to analyze the root causes of these disturbances. Multiple mitigation measures were implemented, including the replacement of vibration-damping fasteners, rail profile adjustment, and rail grinding. The performance of floating rail fasteners was evaluated through vehicle-track coupling analysis and finite element modeling of the tunnel-soil-building system. Post-modification measurements and resident surveys were performed to assess the effectiveness of the implemented solutions. Results showed reductions in indoor vibration levels (VLZmax) of 6.4 dB during daytime and 8.3 dB during nighttime operations, while the equivalent sound pressure levels of structure-borne noise decreased by 1.36 dB (A) and 1.88 dB (A) for daytime and nighttime periods, respectively. Resident feedback confirmed significant improvements in the vibration and noise environment. This case study provides valuable insights for addressing similar vibration and noise issues in Chinese metro systems.
