In this project, a numerical model for the prediction of the railway-induced ground-borne noise and vibration in nearby buildings was implemented in the framework of a web-based computational tool that was developed. The method proposed was computationally efficient and, at the same time, accurate in most of the real scenarios encountered when dealing with railway-induced ground-borne noise and vibration predictions. It was easy to implement and particularly compatible with long sections of track. The computational tool includes the option to evaluate the effectiveness of the different isolation counter measures in the mitigation of railway-induced vibrations, as under-ballast or under-slab mats, rail pads or vibration mitigation screens.
The most important result of the project was a computational tool with a web-based interface that determines the level of vibration and re-radiated noise inside regular buildings located in the surroundings of a railway line, taking into account the characteristics of the rolling stock, the track, the tunnel, the soil and the building. A beta version of the tool was expected at the end of 2021.
