PROBLEM TO BE SOLVED: To provide an earth reinforcing structure which is formed of concrete panels, wherein each concrete panel is made thinner by reducing earth pressure applied to a wall surface, to thereby suppress improvement of foundation ground to a possible minimum extent and cut civil engineering costs. SOLUTION: According to the earth reinforcing structure, by arranging a second pressure bearing plate in the vicinity of a rear surface of each wall face plate, a crushed stone layer is defined between the wall face plate and the second pressure bearing plate which cooperatively constrain the pinched crushed stone layer, and therefore combination of the wall face plate and the crushed stone layer in one body brings about a large resistance against back face earth pressure. Further the back face earth pressure directly acting on the second pressure bearing plate is absorbed by the crushed stone layer exerting a cushioning effect, and therefore the earth pressure acting on the wall face plate is reduced, which leads to thinning of the concrete panel wall face plate.
