Abstract
An earth retaining wall made of stacked tiers of blocks placed side by side to form a wall with a channel extending at least partially along a longitudinal axis of the wall in which the channel define at least two adjacent bearing surfaces and a pathway extending from the channel to an exterior side of the wall. The channel receives an elongate clamping bar that conforms in cross-sectional shape at least relative to the bearing surfaces. A reinforcement sheet wrapped around the elongate connector bar extends through the pathway laterally of the wall. The clamping bar communicates tensile loading of backfill on the reinforcement sheet to the wall. The wall is mechanically stabilized by normal loading from the blocks in the wall above a reinforcement sheet and the tensile loading of the backfill communicated by the clamping bar to the wall. A method of constructing an earth retaining wall and blocks useful in such wall are disclosed.
