土中の応力波減衰に対する考察

Abstract

In this paper the authors are mainly concerned with the propagation problem of stress wavethrough confined soils from a viewpoint of its attenuation by viscous damping. First the analyticalsolution is obtained for semi-infinite one-dimensional rods of some linear viscoelastic models, in thecase of boundary stress forming a spike pulse with exponential decay. The results are confirmed bythe shock tube test originally performed in the authors' laboratory. It is known that this type ofapparatus is satisfactorily applicable to soil dynamics problems as the impact loading technique.
