“…This measure of allocating the rail line in tunnels has the greatest reduction of noise and vibration and can achieve up to 40 dB as aforementioned [107,119]. However, this technology can present some limitations due to the high costs of construction, service and maintenance of the tunnel.…”

Vibration and noise aspects play a relevant role in the lifetime and comfort of urban areas and their residents. Among the different sources, the one coming from the rail transit system will play a central concern in the following years due to its sustainability. Ground-borne vibration and noise assessment as well as techniques to mitigate them become key elements of the environmental impact and the global enlargement planned for the railway industry. This paper aims to describe and compare the different mitigation systems existing and reported in literature through a comprehensive state of the art analysis providing the performance of each measure. First, an introduction to the ground-borne vibration and noise generated from the wheel-rail contact and its propagation through the transmission path is presented. Then, the impact and the different ways of evaluating and assessing these effects are presented, and the insertion loss indicator is introduced. Next, the different mitigation measures at different levels (vehicle, track, transmission path and receiver) are discussed by describing their possible application and their efficiency in terms of insertion loss. Finally, a summary with inputs of how it is possible to address the future of mitigation systems is reported.

“…The study used a noise-map-based approach to provide an efficient method for the evaluation of multiple mitigation measures for noise exposure generated by dense urban railways. Mouzakis et al [18] used finite element analysis software to study the structural vibrations caused by subway operation, and developed a two-dimensional finite element model of the tunnel-soil-building structure. Hammad et al [19] proposed a new mathematical formula based on a binary and adopted integer programming model to optimize the location of a typical railway station construction project.…”

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.

“…Therefore, many researchers have conducted a lot of research on how to use the finite element software for numerical simulation of the vibration problems caused by the subway train operation to the surrounding environment. Balendra T et al Analyzed the vibration of the building structure along the subway caused by subway operation using finite element software to establish a two-dimensional finite element model of tunnel-soil-building structure [11]. Jolles C J C et al Studied the vibration problems caused by train operation in railways and tunnels using the finite element-boundary element coupling model [12].…”

The vibration effect of subway train operation on the adjacent building structure has become one of the outstanding problems in the development of urban underground rail transit and the construction facilities along the line. The new technology of intelligent interconnection provides new ideas for the analysis of the impact of subway vibration, but the network edge side faces many challenges such as connecting massive heterogeneous devices and real-time business. Therefore, in this paper, based on the needs of actual projects, on the basis of edge computing technology, through the field measurement and numerical simulation methods, the typical subway adjacent building structure is affected by the vibration of subway train operation. Edge computing solves the urgent need to realize the function of cloud computing at the edge equipment of massive subway networks, and provides active support for the analysis of the vibration impact of subway train operations on adjacent building structures. Practical case analysis and vibration impact assessment illustrate the superiority of the realization of edge analysis-based metro operation on the vibration analysis of buildings along the line. This method can provide scientific reference and basis for the exhibition of modern subway technology.
