LOCAL SITE EFFECTS ON GROUND MOTION IN SANTIAGO CHILE
|
抄録（英）：
Local site effects on ground motion in Santiago, Chile, are discussed based on observed earthquake ground motions, theoretical response of ground, and microtremor measurements. The spectral ratios of motions at four soil sites with respect to a rock site are calculated to evaluate site amplification factors at the sites. The spectral ratios show that the amplification with respect to the rock site is approximately 1.25 on dense gravel deposits, 2.5 on stiff pumice ground, and 3.5 on silty soft soils. The theoretical response of ground due to SH-waves agrees with the observed spectral ratio at each site. The spectral characteristics of the microtremors at the sites do not show good agreement with those of the spectral ratios.
