The ground‐borne vibration generated by moving trains has become an important environmental problem. Research on mitigation measures has been uninterrupted for decades and has continued to grow rapidly in recent years with the emergence of metamaterial approaches. In this paper, to make relevant newcomers and researchers better understand the development status of mitigation measures in reducing train‐induced ground‐borne vibrations, a brief review is given of the background of train‐induced ground vibration problems, and the design mechanisms of train‐induced ground vibration mitigation measures based on metamaterials. Meanwhile, the results from state‐of‐the‐art research and practice are presented and discussed for each metamaterial mitigation measure for train‐induced ground vibration mitigation. Finally, the existing problems in previous research and future research prospects are summarized.

“…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.

“…The prolonged and repeated exposure to metro-induced vibrations can compromise the functionality of nearby structures, such as opera theatres, and impact the quality of life of local residents (Li et al, 2021;Li et al, 2023;Ma et al, 2016). Consequently, the evaluation of the environmental impact of metro-induced vibrations and the identification of appropriate mitigation strategies have become critical and inevitable concerns (Sun et al, 2022). Hence, it is crucial to perform a comprehensive evaluation of the environmental effects of metro-induced vibrations in the intricate station areas, particularly in scenarios where buildings are situated in close vicinity to the metro line gauge.…”

The vibrations generated by metro operations can cause structural damage and discomfort to occupants adjacent to the metro lines. In this study, a multigrid fully coupled method of metro vehicle-track-station-soil-building systems is proposed to predict and assess building vibrations before construction. This approach facilitates the efficient calculation of the fully coupled system, while ensuring precise simulations through the utilization of multigrid techniques for wheel-rail contact, track, station, soil, and building components. Using the newly-built opera theatre along Beijing metro line 4 as a case, the study demonstrates that the multigrid fully coupled model can predict the dynamics characteristics of metro-induced vibrations and distribution with high accuracy compared with the field tests. Specifically, it was found that metro operations could result in vibrations exceeding specified limits in the opera theatre, particularly at 10 ~ 40 Hz (the building's natural frequency) and 60 ~ 80 Hz (the main frequency band of vibration caused by the metro). Finally, the mechanism of excessive vibration and the effectiveness of targeted vibration mitigation measures were analyzed with the proposed method. These findings have promising implications for wider applications in environmental assessments and control strategies for new metro lines or vibration-sensitive buildings.
