ABSTRACT

The geosynthetics reinforced soil (GRS) retaining structures are composed of reinforced soil and facing structure. Woven geotextile and strip are usually used as reinforcements. A separation technique is in common use in China. The technique is wrapping the geotextile around the face of the wall in the reinforced soil which is connected by strips with facing plate. Between the reinforced soil and facing plate, coarse sand is used as filling material. The facing plate is of a different type, such as modular blocks, full-height concrete plate, concrete blocks, bricks, and shotcrete facing. In most cases, in the retaining walls on-site soil is used as backfill; it even is cohesive or expansive soil. Comparing different gravity walls, the cost of the reinforced wall can be reduced (2060%).
