DYNAMIC CENTRIFUGE MODEL EXPERIMENTS CONCERNING THE SEISMIC PERFORMANCE OF EMBANKMENTS, USING A REINFORCEING BAR

Abstract

In this study, dynamic centrifuge model experiments were carried out to verify the effectiveness of controlling embankment distortion during Level II Earthquake Motion by placing highly versatile reinforcing bars in existing embankments with the aim of ensuring seismic strengthening measures for existing road embankments. As a result, it was confirmed that the installation of reinforcing bars on slopes and beneath the subgrade at specific intervals and placement of bearing pressure plates on the heads of the installed reinforcing bars helped prevent the subsidence of embankments and reduce cracks in the crest of embankments during Level II Earthquake Motion.
