Study of Noise and Vibration Impacts to Buildings Due to Urban Rail Transit and Mitigation Measures

Abstract

The developments in urban rail transit (URT) construction are associated with the benefits of moving people efficiently and the negative impacts of noise and vibrations caused to surroundings. Despite a proliferation of studies conducted throughout the world, very few studies employed the field measurement approach due to various limitations. Using a metropolitan city, Tianjin (China), as an example, field measurement was set up to monitor the indoor vibration and noise spectrum in buildings near urban rapid transit lines to establish a baseline as well as the effectiveness of corresponding mitigation measures, namely wheel-rail polishing and train speed reduction. While our study suggests a maximum 6 dB reduction in indoor vibration, the effectiveness of noise and vibration reduction measures depends on the attenuation of the main frequency corresponding to the secondary radiation noise of the indoor vibration excitation in the building. In our field test, the peaks of the frequency spectrum were found to be 40, 50, 63 and 80 Hz. The secondary radiation noise attenuation and vibration were invariant to the change in frequency spectrum. Mitigation measures such as polishing may cause vibration frequency to peak in non-main frequency spectrums. URT speed reduction will lead to vibration and noise attenuation energy being concentrated at around 50 Hz. Given the presently inconsistent and widely varying industrial and international standards, this study can provide important field measurement data supporting future development in standards, regulation and legislation with respect to URT development, especially in mature townships.

Building the Bridge to a Participatory Citizenship: Curricular Integration of Communal Environmental Issues in School Projects Supported by the Internet of Things

“…The authors used an extensive snowball sampling method to reach city residents. Other studies have been conducted aiming at smart cities’ noise-related issues [ 75 , 76 , 77 , 78 , 79 , 80 , 81 ].…”

Pengukuran Getaran Mekanik Berdasarkan Jenis Bangunan

“…Data hasil pengukuran tingkat getaran yang bersumber dari kereta api di Jakarta dan Semarang menunjukkan tingkat getaran terletak pada rentang frekuensi dominan yang relatif dekat dengan hasil studi Ying Hao dkk. yaitu berada pada sekitar 50 Hz dimana kajian tersebut berada pada kisaran spektrum frekuensi 40, 50, 63 dan 80 Hz (Hao, Qi, Liu, Nian, & Zhang, 2022). Sedangkan nilai tingkat getaran memiliki perbedaan karena jenis kereta api yang diukur yaitu kereta api listrik dan kereta api diesel serta jumlah rangkaian kereta api antara 8 hingga 10 kereta dibandingkan dengan kereta api diesel yang memiliki rangkaian lebih dari 12 kereta/gerbong.…”

Research on vibration characteristics of a straddle-type station induced by moving trains

“…On one hand, vibrations induced by high-speed trains can result in hearing loss, mental stress, sleep quality deterioration, and even cardiovascular diseases [3][4][5]. On the other hand, vibrations from high-speed trains can generate structural noise within the station and surrounding buildings [6,7]. More critically, these vibrations can cause deformation and settlement of the roadbed and tracks, affecting the safe operation of trains and presenting safety concerns for buildings [8][9][10].…”
