構造物基礎―地盤系のランダム応答に関する実験的研究

Abstract

This study deals with experiments on the response of a rigid structural foundation surroundedby surface layers subjected to earthquakes. Vibrating model with a hinge at bottom can ratatoonly about the hinge. Model without a binding force by a hinge can rotato and translate. It isshown that the behavior of the latter in vibration is more affected by that of the surface layer thanthe former is, within the limits of this experiment. The dynamic characteristics of the pore waterpressure and the vibrational earthpressure acting on the model become clear.
