RETAINING WALL STRUCTURE FOR SOIL STABILIZATION

摘要

A retaining wall connection for mechanically stabilized earth structures comprising a plurality of courses (12) of cementations blocks (B) stacked together to define a retaining wall and having a backfill material (M) provided behind the retaining wall. A first layer of geogrid web material (20) has a leading edge disposed between vertically adjacent blocks (B) at a predetermined vertical height of the retaining wall with the trailing edge of the first layer of geogrid web material (20) extending backwardly into the backfill material (M) so as to be engaged thereby. A second layer of geogrid web material (30) is provided so as to overlay and contact the first layer of geogrid web material (20) from the leading edge thereof to at least a medial portion of the first layer of geogrid web material (20) in order to provide a significant increase in the connection strength in the retaining wall and the backfill material (M).
