A series of numerical calculations have been performed to investigate the soil improvement effect on seismic site response. The improved site is composite and has more or less different mechanical properties than the natural soil. The influence of the elastic modulus of the pile, the pile distance ratio, ground motion input, distance to fault rupture and PGA of the earthquakes on seismic response characteristics are especially investigated. The results reveal that the values of the PGA and amplification factor on the surface of the natural soil and improved grounds depend on the period of the site, the period and intensity of the ground motion input. The acceleration response spectra depend on the ground motion input and changing the pile distance ratio doesn't have significant effect on seismic response of site.<\div>
