PURPOSE:To stabilize a slope of the ground by a method in which anchors are penetrated into and fixed to a cut face from the outside of a block contacted with the upper cut face of the ground, and the operations are orderly performed from the upper part to the lower part. CONSTITUTION:The ground 1 is cut off from the upper part, a block 3 is contacted with the upper cut face 2, and anchors 4 are penetrated into the ground from the outside of the block 3 to the upper cut face 2 to fix the block 3 to the cut face 2. The operations are orderly performed from the upper part to the lower part to construct the blocks 3 fixed by the anchors 4 on all of the area to be cut off. The slackening and loosening of the ground 1 after the slope is cut and excavated can therefore be suppressed minimally and the stability of the slope is raised. Also, the amount of the ground 1 to be cut off can be reduced by making the slope steep. |
