FULL SCALE TESTING AND NUMERICAL ANALYSIS FOR POLYMER GRID REINFORCED EMBANKMENT ---PROCEEDINGS OF THE INTERNATIONAL SYMPOSIUM ON THEORY AND PRACTICE OF EARTH REINFORCEMENT, FUKUOKA, KYUSHU, JAPAN, 5-7 OCTOBER 1988

This article described experiments undertaken to: (a) evaluate the effects of polymer grid reinforcement upon the strength and stability of an embankment; and (b) evaluate a design procedure and construction technique for such grid reinforced embankments. A full scale grid model embankment with the following parameters was constructed and tested to failure by changing its slope: (height: 14 m; base width 55 m; slope 1:0.5 up to a height of 6 m and 1:0.8 from 6 m to 14 m). One section of this embankment was not reinforced, and the other 4 sections were reinforced with different amounts (one or two layers) or patterns (chequered or laid in a continuous strip) of grid. The dynamic behaviour of the embankment sections were studied and measurements taken of: the grid and fill material strains; the relative horizontal displacement of the fill material from the slope; and the settlement and horizontal displacement of the embankment. The data obtained were analysed by the finite element method (fem), and the effects of the reinforcement evaluated. Computer simulation of embankment failure using fem was also carried out. The computed results agreed closely with the measured data. The results also showed that embankment strength increased and deformation decreased with increasing reinforcement. The chequered pattern of grid reinforcement was found to be most effective. For the covering abstract of the symposium see IRRD 818063.
