dc.description.abstractThe prediction of vibration impact remains as a complex challenge for designers of new railway infrastructures. Due to the large quantity of parameters involved in the generation, transmission and reception of the vibration waves, it would be necessary to develop a complete study for each potential receiver, which would include: source, soil and building characterization, infrastructure vibration behaviour modelling and, finally, countermeasures influence prediction. This process can turn out to be very costly in terms of both time and money. Therefore, it is usually done only for areas very likely to suffer high vibration levels or for high sensitive buildings (hospital, educational). The CATdBTren project, which has been awarded with R&D funding from the Catalonia Government, is aimed to develop a new prediction tool for evaluating the vibration impact from new railway infrastructures as well as to develop new types of fastening systems having high vibration isolation properties. That tool is intended to be user-friendly and to produce results with average accuracy, so it still will be required detailed studies of problematic areas. In this sense, the software will model the contact forces caused by high-speed, conventional and underground rolling stock. Moreover, it will model the infrastructure’s vibration transmission behaviour, ground vibration propagation, terrain-foundation coupling and building vibration mechanism. The CATdBTren prediction tool will be also capable of estimating the influence of the rolling stock, rail and wheel roughness, fastening system, substructure, soil vibration propagation properties and building characteristics, all in the final vibration impact.
