Abstract

This paper is concerned with theoretical analyses and numerical evaluations based on the wave propagation theory to find dynamic characteristics of an alluvial basin locally situated on a half spatial bedrock due to concentrated loadings on the free surface. The method presented herein is derived from the Aki and Larner's method by releasing the assumption of the repeated irregularities, so that the wave field having localized irregularities can be evaluated. The numerical analyses show that the amplification effects are obvious on the free surface inside the alluvial sediment and the subsurface structure influences the seismic behavior observed on the surface.

Dynamical Behavior of a Slightly Alluvial Basin Due to Concentrated Turbulence

St. Louis, Missouri

This paper is concerned with theoretical analyses and numerical evaluations based on the wave propagation theory to find dynamic characteristics of an alluvial basin locally situated on a half spatial bedrock due to concentrated loadings on the free surface. The method presented herein is derived from the Aki and Larner's method by releasing the assumption of the repeated irregularities, so that the wave field having localized irregularities can be evaluated. The numerical analyses show that the amplification effects are obvious on the free surface inside the alluvial sediment and the subsurface structure influences the seismic behavior observed on the surface.
