effectively than by extending all the reinforcements moderately. On the
other hand, effects of shear deformation of the reinforced backfill,
which are not considered in the current design procedures, cannot
be ignored,
in particular
for
reinforced soil RWs with longer
reinforcements.
ACKNOWLEDGMENTS
