The arch- shaped structures A are fixed to the ground with anchors 3. Rock bolts 7 are driven to the upper part of the slope. Concrete 8 is placed to gaps between the arch-shaped structures A and overhanging parts of the slope. The arch- shaped structures A can be constituted of precast concrete blocks. Accordingly, the collapse of the upper slope can be prevented with the rock bolts 7, the overhanging part of the slope can be borne on the arch-shaped structures A from below.
