phisticated cultures to reinforce mud bricks and mud walls. Nevertheless, in spite of this long usage, French architect H. Vidal was able to obtain a patent (ca. mid1960s) on the general configuration of , which he termed “reinforced earth”. We see three basic ponents in this figure. ① the earth fill—usually select granular material with less than 15 percent passing sieve. ② reinforcement—strips or rods of metal, strips or sheets of geotextiles, wire grids, or chain link fencing or geogrids (grids made from plastic) fastened to the facing unit and extending into the backfill some distance. Vidal used only metal strips. ③ facing unit—not necessary but usually used to maintain appearance and to avoid soil erosion between the reinforcements. These three ponents are bined to form a wall whose side view is shown in . When wire mesh or other reinforcement with discontinuities (grid voids) is used, apportion may be bent , similar to the sheet of , to form a facing unit. Gridtype reinforcements strengthen the soil through a bination of friction and passive pressure pullout resistance. The bentup portio。
