Geogrid reinforced soil double facing wall consists of the outer wall built of concrete panels, the inner wall of geogrid reinforced backfill and vertical drainage layer between outer and inner walls. Because the wall is often constructed on steep slope and becomes large scale, it affects the road traffic and neighboring structure when the wall deforms due to disaster. Repairability of the wall is influenced by scale of the wall, construction condition and deformation level. Additionally, the frequency of occurrence of heavy rainfall increases so that it needs to define the repaired procedure for the reinforced soil wall. This paper proposes the repaired procedure for the reinforced soil wall appropriate for damage level based on actual repair works for damaged wall due to rain infiltration and earthquake.
