Segmental retaining wall (SRWs) (primarily with precast concrete blocks facing) reinforced by geogrids or geotextiles were in a period of enormous growth. A vertical model retaining wall, 3m high and 5m long, was constructed by reinforcing the backfill with two sides' vertical anchored blocks. The cohesionless earth backfill, available at the site of construction, was reinforced by metallic bars reinforcement that were attached to the wall face blocks. The reinforcing layers were instrumented with strain gauges, tensile geogrid load transducers and horizontal displacement sensors. In addition, total soil pressure transducers were installed inside the structure to monitor the internal state...
