RETAINING WALLS CONSTRUCTED ON THE "REINFORCED EARTH" PRINCIPLE

UEBER STUETZWAENDE IN DER BAUWEISE "BEWEHRTE FRDE (LA TERRE ARMEE)"

Retaining walls constructed on the "reinforced earth" principle are walls anchored at several points, constructed in units and anchored by relatively closely spaced friction bands. The earth pressure is partly taken up by the friction of the bands. This method of construction has been in operation in some countries for ten years now and has proved itself economical. The wall itself consists of 10 M long, 33 cm wide, half elliptical galvanised 3 mm thick metal sheets fitted with flanges. Overlaps at the edges prevent the escape of soil. For aesthetic reasons wall panels of concrete have also been developed. The friction bands are cut from galvanised steel plates in widths of 6 - 12 cms and lengths up to 25 M. Their thickness is 3 mm. The fill material should consist of a cohesionless soil with a high shear strength. It is laid in layers and compacted. The coefficient of friction between soil and steel band is taken as 0.4. This is the lowest value obtained from tests. The calculation of the internal and external stability is given. The influence of settlements is discussed. /TRRL/
