Abstract

Bridges are important element of transport system. If they are damaged, they must be replaced quickly. For this purpose, a number of temporary engineer equipment is used. Also, the bridge in the Czech Republic by small town Hustopeče nad Bečvou was replaced by this way. But the temporary solution has become a permanent solution. Engineer constructions, however, have a number of shortages and therefore, it was decided to modify them using anti-vibration mats. This is the first application of this type of mats, and it is necessary to detect any adverse impact on the bridge and its surroundings. The paper presents an analysis of the dynamic response upper layers of the bridge geological surroundings. The experimental seismic measurements were realized before mats installation and after it. All measurements were performed in amplitude and frequency area and the results were drawn as attenuation curves. The vibrations were also analysed according to the Czech relevant standards.
