dcterms:description
The paper discusses measures to reduce the negative effects of tram traffic on residential house in Ostrava, where the tram line passes through the street area located under the structure of the house see Figure 1.Fig. 1 House No. 1340 in Ostrava affected by vibrations from rail transportThe lines of urban railways are often kept at densely built-up areas, often in close proximity to the buildings. It is necessary to put a high emphasis on protection against noise and vibration. In case of structures for residential buildings it has a negative effect on residents. An efficient way to reduce the vibration levels of the protected structure and thus the secondary noise is elastic foundation structure as a whole to its support structure. But in practice, we need to solve the problem of the ex post, i.e. when the structure of a residential building already exists.To reduce the transmission of vibrations to the structure was carried out technical measures for vibration attenuation along the route of the spread it is the path from the source to the protected structure. Railway track was imposed on rubber anti-vibration mats under gravel bed of tram line. Furthermore, the test sections were established in order to test the application of different materials used as a grout space between the rails and the surrounding environment and the reference section to compare the resulting data.Subsequently was held the measurement of noise and vibration. Vibrations were measured on the own construction of the house, also on the communication - vertical vibration near the track (30 cm far from the running rail track), these data present the transmission of vibration from the rail and sleepers in the immediate surroundings, measuring the vertical vibrations of the road (150 cm far from the running rail track in place that was not affected by reconstruction), these data present the transmission of vibration to the subsoil neighborhood.
