“…The track model includes the rail and the rubber cushions and fasteners under the rail, and assumes that it is an elastic long beam supported by a 3-layer mass-spring-damper system, in which the elastic long beam simulates the steel rail and a 3-layer mass-spring-damper The system simulates the under-rail cushion, sleepers and track bed respectively. Using the above vehicle-track system dynamic analysis model, the finite element numerical algorithm is used to obtain the load acting on the base as shown in Figure 3 [23].…”

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.

“…A reliable forecast requires a large amount of empirical data. It should cover all typical building structures as well as the mutual location of the vibration source and buildings [5,6,8]. This work presents results of vibration acceleration levels measured on the ground and on the foundation of a building near the tunnels of a small underground.…”

This paper presents the problem of rail transport vibration transmission from the ground to building foundations. Field measurement results of vibration parameters on the ground near buildings and their foundations have been covered in this study. It has been shown that vibrations at the foundation of a building are much smaller than vibrations on the ground. The most intense vibrations on the foundation slab occur in the vertical direction. Comparison with other experimental data on vibration transfer from the ground to buildings structures has been made. The data obtained can be utilized in designing vibration protection measures and to analytically predict vibration effects in buildings. This analysis can be performed after measuring the vibration of rail transport on the ground surface.

“…The vibration level depends on many factors such as train speed, ground condition, type of structure concerned etc. The effect of ground borne vibration on the building in surrounding areas has been studied in previous literature (Kouroussis et al, 2013;Zou et al, 2015;Zou et al, 2017;Vogiatzis and Mouzakis, 2017). Even though the ground borne vibration might not cause damage to the structure, this may cause annoyance to the people in the building (Suhairy, 2000;Lopes et al, 2016).…”

At present, railway infrastructure experiences harsh environments and aggressive loading conditions from increased traffic and load demands. Ground borne vibration has become one of these environmental challenges. Overhead line equipment (OHLE) provides electric power to the train and is, for one or two tracks, normally supported by cantilever masts. A cantilever mast, which is made of H-section steel, is slender and has a poor dynamic behaviour by nature. It can be seen from the literature that ground borne vibrations cause annoyance to people in surrounding areas especially in buildings. Nonetheless, mast structures, which are located nearest and alongside the railway track, have not been fully studied in terms of their dynamic behaviour. This paper presents the effects of ground borne vibrations generated by high speed trains on cantilever masts and contact wire located alongside railway tracks. Ground borne vibration velocities at various train speeds, from 100 km/h to 300 km/h, are considered based on the consideration of semi-empirical models for predicting low frequency vibration on ground. A three-dimensional mast structure with varying soil stiffness is made using a finite element model. The displacement measured is located at the end of cantilever mast which is the position of contact wire. The construction tolerance of contact stagger is used as an allowable movement of contact wire in transverse direction. The results show that the effect of vibration velocity from train on the transverse direction of mast structure is greater than that on the longitudinal direction. Moreover, the results obtained indicate that the ground bourn vibrations caused by high speed train are not strong enough to cause damage to the contact wire. The outcome of this study will help engineers improve the design standard of cantilever mast considering the effect of ground borne vibration as preliminary parameter for construction tolerances.
