“…With the development of urban rail transit, the problems of train-induced tunnel and building vibrations have received increasing attention recently [1][2][3][4][5]. These environmental issues have potential impacts on the nearby residents [6][7][8][9], the long-term protection of historic buildings [10][11][12][13], and the operation of precision instruments [14,15]. To control the train-induced vibrations, various types of mitigation measures can be taken: wheel profiling and rail grinding [16][17][18][19], designing vibration mitigation measures on the track [20,21], using a propagation path [22,23], and using vibration receivers [24].…”

Kelvin’s model is widely used to simulate the dynamic characteristic of a resilient mat under a slab track. To develop an effective calculation model for a resilient mat using a solid element, a three-parameter viscoelasticity model (3PVM) was employed. With the help of the user-defined material mechanical behavior, the proposed model was implemented in software ABAQUS. To validate the model, a laboratory test was performed on a slab track with a resilient mat. Then, a finite element model of the track-tunnel-soil system was built. The calculation results using the 3PVM was compared with those using Kelvin’s model and the test results. The results indicate that the 3PVM can better reflect the dynamic characteristics of resilient mat than Kelvin’s model, especially over 10 Hz. Compared with the test results, the 3PVM has an average error of 2.7 dB and a max error of 7.9 dB at 5 Hz.

“…In general, a good number of researches have been done that examine the issue of noise pollution and vibrations caused by railways. Some of this research has only focused on noise pollution caused by railways (Grubliauskas et al, 2014 ; Zhang & Ma, 2021 ), and some other only deals with rail vibrations (Connolly et al, 2016 ; Peris et al, 2012 , 2014 ; Sharp et al, 2014 ) and there is a limited number of papers which investigated as a novel approach, the efficiency of combining railway vibration and noise barriers (Maigrot et al, 2020 ; Nering et al, 2020 ; Peplow et al, 2021 ).…”

In this study, the effects of noise and vibrations caused by railways on the lives of residents around the railways in districts 17 and 18 of Tehran, the capital of Iran which amounts to about 700,000 people, are investigated. In the first stage the actual level of noise was measured at various points which showed above standard levels. Afterward, the authors developed a questionnaire and the survey was conducted from 376 residents. The findings of this study show that the most important factor for the residents adjacent to the railway line is the need for action by the country's railway authorities to reduce and control the adverse effects of noise and vibration. Also, the analysis of inferential statistics performed by chi-square test shows that the variables of gender and proximity of residence or workplace or both to the railway do not affect any of the railway noise or vibration dissatisfaction. The age variable also has no effect on noise dissatisfaction but does impact on vibration. Finally, distance from the railway affects both disaffection from noise and vibration.

“…One is using the vibration isolation devices at the building base ( 1 – 4 ). Another is to suppress the vibration and noise induced by railways by improving the soil or using ground barriers between buildings and rail lines ( 5 – 8 ). Finally, different vibration reduction measures placed in the subway tunnel can be adopted.…”

Damping fasteners provide vibration isolation to railway tracks because of their low vertical stiffness and improve the in-service performance of the tracks. In this paper, a new type of high lateral stiffness and vertical damping fastener is developed. First, the vibration suppression frequency band of the new fastener was determined from a field test, the design vertical stiffness was determined by calculating the P2 resonance frequency, and the vertical stiffness before and after a fatigue load test was found. Then, field experiments were carried out in buildings with known excessive subway train-induced vibration problems to assess the effectiveness of the proposed fastener, which showed that the damping fasteners reduced the vertical and transverse vibrations of the tunnel wall by 10 dB without increasing the transverse displacements of the rail. Furthermore, the structure-borne noise reduction in all measured buildings exceeded 3 dB. The study demonstrated that the replacement of novel damping fasteners is a feasible solution for controlling vibrations and noise in buildings adjacent to subway lines.
