PURPOSE: A retaining-wall block is provided to facilitate the construction of a vertical or sloped retaining-wall while a depressed part and a projection are formed on the block to be assembled. CONSTITUTION: A side projection(110) is formed on the upper part of one side of a retaining-wall block(100). A side depressed-part(120) is formed in hemisphere shape, and made in the lower part of the same side as the side projection. Upper and lower depressed parts(130,140) are formed on the upper and lower parts of the other side of the retaining-wall block. A central hollow part(150) is formed at the center of the retaining-wall block. At the bottom of the retaining-wall block, several projections are shaped. More than two edge projections(160) are formed around both edges of the retaining-wall block, and a central projection(170) is made at the center of the lower part. The retaining-wall blocks are constructed also in arc shape.
