Vplyv litologického prostredia na šírenie a útlm indukovaných seizmických otrasov

Abstract

Secondary generated seismic waves, which are used in near seismic survey of upper parts of Earth crust at the present, can evoked unfavourable fall on buildings and others engineering constructions. For all that it is needed experimental measurement and monitoring. In year 2006, company Nafta a. s. realized seismic survey in south part of East Slovak Basin and northern part of Viennese Basin. Measurements of seismic effects on engineering object were carried out during survey time. These results suggested possible negative impact invocation of seismic vibration. Law of seismic wave absorption was defined from experimental measurements. Presentation suggests measurement methodology and documents contrast in velocity of extension wave in different geological environments.
