External sources such as traffic and construction work cause noise vibration in nearby buildings, potentially annoying human residents. Today, almost every fifth European is harmfully affected by vibration. Wave barriers placed on or embedded within the soil between source receiver can mitigate transmission of ground vibration, airborne be reduced a similar manner with screen acting barrier. As...

A three-dimensional finite element model was developed to investigate dynamic response of track-embankment-ground system subjected to moving loads caused by high speed trains. The track-embankment-ground systems such as the sleepers, the ballast, the embankment, and the ground are represented by 8-noded solid elements. The infinite elements are used to represent the infinite boundary condition ...

During the last decades, the railway traffic in densely populated areas has increased. At the same time, passenger trains have become faster and freight trains have become heavier. Consequently, trains are an increasing source of ground vibration, which may be a nuisance to people, buildings and sensitive equipment. In this research, a two-dimensional dynamic system, including underground train...

one of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. this is addressed in this research...

This article presents a numerical study that aims to explore the impacts of stiffness elastomeric bearings on dynamic behavior railway bridges under train-induced vibrations. For this purpose, finite element code considers vehicle–bridge interaction using coupled approach was developed. The software validated by comparing response analytical solution. analysis single- and multi-span with varyin...

This paper illustrates the phenomenon of the critical speed in the range 100300 km/h. A real explanation and a precise calculation of the critical speed seems to rest an unresolved problem in many cases. Some authors, analogous to “Mach effect”, have attributed this phenomenon to the reaching the Rayleigh wave speed of substructure by trains. But this explanation can’t be thorough in many cases...
