MODEL LOADING TESTS OF REINFORCED SLOPE WITH STEEL BARS ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

Vertical loading tests on reinforced slope models were carried out in order to study the effects of aluminium bar reinforcement in a sandy slope. The model slopes, with the following dimensions (20 cm width; 75 cm height; 210 cm length) were made by compacting 15 cm thick layers of sand in a steel frame. The aluminium plate reinforcing members were placed before compaction. The placement angles of the reinforcing members was varied from: sloping upwards at 20 deg; horizontal; and sloping downwards at 20 deg. Load was applied via a 27 x 105 cm load plate in steps of 0.5 kgf per square centimetre and was maintained until the settlement rate was less than 0.5% per minute at each loading step. When the loading approached the yield condition, loading steps were reduced to 0.25 kgf per square centimetre. The deformation of the load plate and the slope surface, and the reinforcement plate stresses were measured. It was found that: (a) the effect of the reinforcement increased as the bars were moved from horizontal, to downwards, and finally, upwards; (b) the largest increase of axial stress was found to be between the slip surfaces of reinforced and un-reinforced slopes; and (c) the bending and shearing resistance of the reinforcement plates contributed little to the reinforcing effect.
