Abstract
Vibrations of the bedrock due to earthquakes are transferred to the ground level via different soil layers. The arrived waves in the ground surface which affect the superstructures are usually stronger than those induced in the bedrock, depending on the geological and geotechnical characteristics of the soil layers. In this paper the influence of different geotechnical parameters of a site on the amplification of earthquake waves are investigated using the mathematical equations of wave’s propagation in a visco-elastic half-space medium. A special computer software was used to analyze the geotechnical data of a site in the western part of Tehran. The obtained results are illustrated as the response spectra in the ground surface to evaluate the effect of each parameter on the earthquake amplification. Finally the amplification factor of the site was calculated by comparing the bedrock and the ground accelerations obtained from the analysis.
