“…The trains operating in the Nanchang subway are taken as the research object [8], based on the theory of vehicle-rail coupling dynamics [9]. The vehicle used in Nanchang subway is a B-type train, in which the carriage is a vibration system with 10 degrees of freedom composed of two bogies and four-wheel pairs, and connected by the main suspension and sub-suspension system [10]. Considering the heavy load condition for the moving train, the static axle weight is 133.8kN, and the Hertz nonlinear contact theory is used to determine the interaction between the wheels and rails.…”

The rapid development of subway construction inevitably leads to the subway lines traversing through or adjoining the buildings. However, current research primarily focuses on the train-induced ground-borne or building with shallow foundation vibrations, with a relatively limited investigation into the vibration pertaining to the building with pile foundation. A vibration analysis model of a building with pile foundation adjacent to a subway is established in this study using the finite element method, and the effects of various factors on the vibration of the building are analyzed, then the prediction of building vibration characteristics is also carried out by combining artificial intelligence methods. The results show that the building floor has an amplifying effect on the vibration acceleration level and Z-vibration level in the high frequency range, and the vibration energy attenuation at high frequencies is faster in the building with pile foundation compared to the building with shallow foundation. In the meantime, it shows that the GA-BP model is capable of effectively capturing the vibration characteristics of the building with pile foundation within the dominant frequency range. and the vibration of the building with pile foundation can be predicted not only by parameters such as train speed, soil and structure parameters but also by train-induced ground-borne vibration, which provides the possibility of simplifying the process of vibration prediction process and enhancing the practical application.

“…The impact of train-induced vibration in adjacent buildings is affected by many factors, not only from the track [ 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ] but also from the geological condition [ 20 , 21 , 22 , 23 ] and the structure itself [ 27 , 31 , 32 ]. Therefore, the ground vibration measurement results are not enough to assess the expected vibration acceleration level in the theater.…”

“…The impact factors include but are not limited to the change of wheel and rail profiles due to wear and maintenance [ 16 ], the temperature force in the rail [ 17 ], different types of track irregularities [ 18 ] and installation quality of fastening clips [ 19 ], etc. Regarding the propagation path of the vibration, which is mainly the surrounding rock and soil of the railway foundation, the physical properties [ 20 , 21 ] as well as distribution of soil and rock layers [ 20 , 22 ] are considered as influential factors that may contribute to the attenuation of vibration. In the aspect of vibration and noise receivers, the foundation type [ 23 ], the height and weight of the structure [ 24 ], the position of measurement points [ 24 , 25 , 26 ] and the vibration isolation design [ 27 , 28 ], etc., can all influence the vibration and noise level.…”

This study presents the analogical assessment of the train-induced vibration and radiated noise in a proposed theater. The theater is to be constructed in a region with crowded metro lines, and the assessment is implemented in an analogical building with comparable structural type and metro condition. Prior to the assessment, the comparability of the analogical building with the theater is validated using the train-induced ground vibration. With the same horizontal distance from the metro line, the train-induced vibration level in the analogical building is 9 dB higher than that in the construction site of the theater. Such results indicate that the lack of soil layers may lead to a dramatic increase in train-induced vibration in the building. In the staircase of the analogical building, the train-induced radiated noise reached 55 dB (A), which is 10 dB (A) higher than the daytime allowable level. As the most important indicator, the noise rating number in the cinema of the analogical building is NR-43, which put forward an enormous challenge on the construction of the theater with a denoise demand of 23 dB. The analogical method applied in this study provides an effective and practical way for the assessment of train-induced vibration and radiated noise in proposed vibration-sensitive buildings. The assessment results that provide necessary reference and support for the anti-vibration design will help guarantee the stage effect of the theater.

“…These vibrations are known as ‘ground-borne vibrations’, and may also result in ground-borne noise (aka ‘re-radiated noise’), if they reach nearby buildings and cause the walls and floors to shake (Connolly et al, 2016 ). Good foundations reduce vibration transmission from ground soil up into the building and lead to a lower level of structure-radiated noise (Zou et al, 2020 ).…”

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.
