抄録

A generation method of broadband statistical Green's functions of horizontal and vertical ground motions is proposed. The method includs following new contents.<br> 1. Near-filed and intermediate terms as well as the far filed term of the source spectra are considered.<br> 2. The ratio of corner frequency of P-wave to that of S-wave is assumed to be the ratio of P-wave velocity to S-wave velocity. <br>3. Scattering effects are considered into the path spectra in the high-frequency range. <br>4. Site effects for vertical motions are represented by 1-D theoretical amplification factors assuming obliquely incidence P- and S-waves in the low-frequency range and vertical incidence P-wave in the high-frequency range.<br>The method is verified by comparison between the generated statistical Green's functions and near-field records during the 1998 Miyagiken-Nanbu earthquake with M_J=5.2.
