“…Taking basic precautions in the construction phase could increase the comfort level of passengers and people who live in buildings near the railway line. To reduce the vibration effects, different superstructure types are developed such as single (just rail pads) or double layered pads (rail pads with baseplate pads) [3][4][5], mass-spring systems [6], floating slabs [3,7,8], under ballast mats [9,10].…”

“…The vibrations below 100 Hz are important when the effects of railway vibrations on the comfort of passengers and people who live in the environment, and robustness of the environmental buildings are examined [12][13][14][15]. Taking this information into consideration, research and vibration measurement implementations were carried out on the railway and its environment [7,[16][17][18][19]. In addition, several theoretical and analytical studies have been conducted to reduce the effects of railway-induced vibrations since Bata's study of the effects of transport vibrations on buildings [3-6, 8-11, 20-24].…”

“…Even though much theoretical research has been carried out on the subject in the past, the number of experimental studies that investigate the effects of railway-induced vibrations is under researched. The effectiveness of floating slab track (FST) system in Konya Light Rail was investigated by Dere [7]. In Dere's study, above 50 Hz vertical vibrations were suppressed successfully, contrary to below 1 Hz vibrations using FST.…”

Railway-induced vibrations are one of the major problems that need to be suppressed for the passengers or people who are living around the railway. It is essential that the vibrations are first tried to be suppressed on the source, railway. Thus, the railway superstructure components contain various elastic elements used in vibration insulation, such as rail pads. In this study, two different railway superstructures used in Istanbul railway traffic were tested while passing the railway vehicle at various speeds, and the vibrations generated by the wheel-rail interaction were compared regarding passenger comfort and the environment in compliance with the relevant standards. Used railway superstructures to compare the propagated vibrations are constructions with single and double elastomeric layers installed on the same line, sequentially. In this experimental benchmarking study which contains some evaluations according to standards, the behaviour of these two railway superstructure types in terms of vibration insulation in light metro lines is revealed using measurement results. Consequently, when the double-layered elastomer is used instead of a single-layered in the superstructure, the comfort level of the people living around the line is improved as up to 64% and the comfort level of the passengers is improved as up to 54%. In addition, in terms of the safety investigations of the buildings around the line, a meaningful decrease in vibrations greater than 70 Hz is observed and it is concluded that residential buildings could be built up to 5 m distance.

“…Lombaert et al [8] established a 3D numerical model for the investigation of effectiveness of a resilient-mat floating slab track on the control of ground-borne vibrations. A field test was carried out by Dere [9] to evaluate the effectiveness of vibration reduction for the floating slab track. e steelspring floating slab track was suggested by Ma et al [10] on controlling vibrations of overlying historic architecture generated by metro lines.…”

A theoretical model incorporating the moving train, the railway track, and the elevated viaduct is established and then solved using periodic theory in this paper. The vertical wheel/rail forces and the dynamic responses of track and viaduct girder are obtained and compared for three different types of tracks, i.e., the double-block ballastless track, the rubber-pad floating slab track, and the steel-spring floating slab track. It is observed that the rubber-pad and steel-spring floating slab tracks can reduce more than 10% of the wheel/rail force and the reaction force at girder supports, when compared to those of the double-block ballastless track. Especially, the steel-spring floating slab track develops an uplifting force larger than the installation force of the fastening clip, which may cause failure of the rail fastening system.

“…Many vibration countermeasures have been developed to reduce the vibration effects from railways. Various types of isolation are discussed in the literature, e.g., open and filled trenches, concrete walls or piles, and flexible gas cushions [2][3][4][5][6][7]. Among these types of isolation, the open trench has been demonstrated as an effective intervention, and it is the most common intervention in practical traffic applications, especially for mitigating vertical vibrations [6].…”

In this paper, we analyse the mitigation effects of open trenches on the vibrations induced by subway trains. The study is performed by using both physical model tests and numerical simulations. The effectiveness is evaluated by calculating the frequency response function (FRF) and the vibration acceleration peak (VAP) in both time and frequency domains. The experimental and numerical results demonstrate that the open trench has clear effects on the dynamic soil response. Both time and frequency domain results suggest that the dynamic response of the soils beyond the open trenches could be significantly affected, due to the existence of the open trench. According to the frequency domain analysis, the inclusion of open trenches could effectively reduce the soil response in a higher frequency range. Due to reflection effects at the boundaries of the trench, an amplification of the soil response in front of the open trench is observed. Parametric study by means of numerical simulations is also performed. The width of the open trench demonstrates negligible effects on the dynamic soil response, whilst the trench depth exhibits a large influence on the trench isolation performance. With an increase in the trench depth, the isolation performance is significantly improved. It is concluded that the open trenches perform well as an isolation barrier, in mitigating the vibration induced by subway trains.
