Abstract

The planning of foundations for equipment sensitive to vibrations requires a thorough dynamic investigation of the proposed location of the foundation with regard to the effect of already existing or additional vibration sources. This paper discusses the analyses performed for a power plant facility that is subjected to blasting-induced vibration from an adjacent quarry. To assess the level of seismic excitation at the site due to blasting activities in the quarry, an extensive ground vibration-monitoring program was carried out. This program included initial blast monitoring of production blasts at the future turbine location, and the development of a final design acceleration time-history. The results of the vibration-monitoring program showed that the production blasts displayed extremely variable vibrat
