水平加振力による多層構造地盤の震動特性について

Abstract

Integral expressions for the displacement fields produced by a horizontal point force onthe surface are derived by using a technique applied first by N.A. Haskell to seismological problem, when an elastic isotropic solid half space is composed of homogeneous layers with parallelwhen an elastic isotropic solid half space is composed of homogeneous layers with parallel bound-aries. The integrals for the fields near the source are exactly calculated by digital computer forthe branch line integral and the residues and for the integral along the real axis.The numerical results are compared with spectra in the case where an infinite train ofharmonic plane SH waves is vertically transmitted to the surface layers.
