PROBLEM TO BE SOLVED: To construct a retaining wall having higher earthquake resistance than that of a retaining wall singly using retaining wall blocks by using both of retaining wall blocks and solid geocells and organically combining them and crushed stones with each other.SOLUTION: Retaining wall blocks 1 each having a faceplate 2, a counterfort plate 3 standing lower than the faceplate, and a tie plate; solid geocells 10 each having a plurality of cell dead spaces 13; and single-grain-sized crushed stones 17 are used in a retaining wall. The retaining wall block is installed at the front position of the slope face 20. The solid geocell is disposed above the upper end level of the counterfort plate and below the upper end level of the faceplate so as to overlap a block dead space 6 and a rear dead space 24. Only the single-grain-sized crushed stones 17 are backfilled in an entire region of the faceplate and the slope face, thereby constructing one stage. A next stage is similarly constructed on the stage. Third and subsequent stages are constructed by repeating the above-described method. |
