Buildings are subject to vibrations caused by the environment, such as those from industry,
constructions, vehicle traffic, among others. These vibrations can damage the building over time or cause
discomfort for its users. The construction of buildings near railway lines is a reality increasingly present in large
and small cities around the world. This work shows an analytical methodology for predicting velocities and
accelerations in the soil caused by rail traffic, which affect nearby buildings, people or nearby improvements.
Using equations validated in the literature, an analysis of the physical vibrations and noise generated by train traffic
will be performed. The objective is to achieve a better understanding of the propagation of vibrations and to make
better use of regions close to the railway lines. They are verified for four soil types in order to evaluate their
influence on the propagation of the velocity and instantaneous acceleration in the horizontal axis of induced
vibration in the medium. Other parameters are also analyzed, such as the distance from the railway, train speed
and load, and the type of track. These analyses are performed using a mathematical program. In this way, it is
expected to contribute to the standardization and understanding of the behavior and propagation of vibrations
caused by the railways.
