Abstract

For the widening and slope surface repair of the embankment, cover soil is placed on the existing embankment slope. To stabilize the cover soil, the slope stabilization method we have developed for existing embankments using small diameter steel pipes with blades is adopted. Since the pipes are perforated in order to provide drainage function, the pipes are installed laterally. In this study, to verify reinforcing effects of laterally installed steel pipes into the embankment, unloading experiments are carried out in the geotechnical centrifuge and on an actual embankment.
