PROBLEM TO BE SOLVED: To provide a reinforcement structure of a slope face capable of restraining collapse of the slope face of land in disaster time in the present invention.SOLUTION: A reinforcement structure of the present invention is a structure for reinforcing at least a part of a slope face of land, and comprises a plurality of sandbags placed in a step shape in a reinforcement part of the slope face, one or a plurality of presser plates horizontally arranged on a terrace surface of the plurality of sandbags and compressing the plurality of sandbags in the vertical direction and one or a plurality of anchors for fixing the sandbags to the ground. The reinforcement structure is desirably formed in a multistage along the slope face. The reinforcement structure is desirably provided on the slope tip of the slope face. One or the plurality of anchors are desirably driven in up to the lower ground. The plurality of sandbags are desirably a substantially columnar shape in a pressure-unloaded state. The plurality of sandbags of the substantially columnar shape are desirably placed at its axial direction in the direction along a contour line of the slope face in the pressure-unloaded state.SELECTED DRAWING: Figure 1 【課題】本発明は、災害時等における土地の斜面の崩壊を抑制できる斜面の補強構造を提供することを課題とする。【解決手段】本発明の補強構造は、土地の斜面の少なくとも一部を補強する構造であって、上記斜面の補強部分に段状に載置される複数の土嚢と、複数の上記土嚢のテラス面に水平に配設され、複数の上記土嚢を上下方向に圧縮する１又は複数の押さえ板と、地盤に対して上記土嚢を固定するための１又は複数のアンカーとを備える。当該補強構造は上記斜面に沿って多段に形成されることが好ましい。当該補強構造は、斜面の法先に設けられることが好ましい。１又は複数のアンカーが下方の地盤まで打ち込まれていることが好ましい。複数の土嚢が非圧力負荷状態で略円柱状であることが好ましい。非圧力負荷状態で略円柱状の複数の上記土嚢が、その軸方向が上記斜面の等高線と沿う方向に載置されていることが好ましい。【選択図】図１
