Definitions

a reinforced earth structure comprises a mass of particles normally extracted from the natural ground and reinforcing straps embedded in the mass, said reinforcing straps providing frictional contact with the grains or particles. These reinforcements ensure that the structure is stable.
the free vertical surface of the reinforced structure is faced with cladding or skin for retaining the particles which are located in the vicinity of the said free surface and which are therefore not subject to the frictional retaining effect of the reinforcing straps.
the above mentioned patent discloses cladding consisting of U-section elements in superimposed relation, having adjacent flanges of elements in contact with one another.
Israel Patent No. 50515 discloses a specific type of reinforcing strap having traverse ribs extending over the full length of the strip to provide better friction with earth and improve the reinforcement for structures of reinforced earth.
Today slabs of the type disclosed in Israel Patent 35046 are the most common cladding for reinforced earth structures. These slab claddings are usually arranged in an interlocking manner with the edges of one slab engaging those of the adjacent slab in tongue and groove arrangement. Reinforced earth can thus be prepared with a vertical end surface of 20 meters and more, having a cladding or facing of concrete slabs layered one upon the other to the very top of the structure, each concrete slab providing a barrier for lateral displacement of the ground adjacent to it, to which it is anchored by reinforcing straps.
the concrete slab claddings have heretofore been used exclusively as a facing for reinforced structures. It was thought that the cladding is not capable of supporting vertical loads, since it is composed of discrete elements with flexible joints between them. All vertical loads associated with reinforced earth structures were applied on the earth at the back of the cladding or transferred to underlying strata by other means such as piles or columns.
suitable cladding of reinforced earth structures can serve as load-supporting walls, capable of receiving vertical loads.
the horizontal forces in the straps, which are anchored to the cladding elements are translated into vertical reactions which enable the discrete elements to accept substantial vertical forces with very small deflections well within tolerable limits.
suitable cladding of reinforced earth structures can serve not only as facing for anchorage of the straps to prevent lateral displacement of the adjacent earth, but also as vertical load supporting walls, although such walls are not verticically rigid, but rather comprise multiple tiers of concrete slabs disposed one on the other.
FIG. 5 Detailed construction of slab 4 is illustrated in Figure 5.
the cross-sectional joints 31, 32, 33 and 34 have a tongue 35 for engaging an adjacent slab in a corresponding groove 36 in a tongue and groove arrangement.
Anchors 37 are embedded in the concrete slab 4, as can better be seen in Figure 6.
Flexible reinforcing straps 38 are fixed to the anchors 37 by means of bolts 39.
Horizontal steel plate flanges 40 at the connection between the cladding element and the strap can optionally be introduced to further improve the interaction between the horizontal force exerted by the strap and the resistance to vertical forces applied on the cladding elements.
the vertical deflections under the static vertical loads as well as horizontal deformations of a structure subjected to blast loading will be further reduced, enabling construction of vertical load supporting walls without building a foundation.
bomb shelters made of such structures can safely be provided with stone tile flooring, which is not the case with conventionally constructed bomb shelters.
Other applications of this invention include the construction of bridge abutments with shorter spans, thus eliminating elaborate support platforms which are presently required for carrying loads on reinforced earth.
