To provide a sloped face stabilization structure securely preventing a sloped unstable ground with a shallow surface layer thickness from sliding at low cost.SOLUTION: In a sloped face stabilization structure, a net 4 is coated on a surface side of an unstable layer 2 with a surface layer of 0.5 m or less in a sloped ground 3, and the net 4 is tensioned to be fixed by many anchors 6 to a board. An area surrounded by four anchors 6 is isolated from a peripheral area as a slide unit 11, by disposing the anchors 6 at apex positions of a substantial square and making one diagonal line of the square be along a sliding direction of the unstable layer 2. Widths W1, W2 of the slide unit 11 are 3 m or less between each apex. A crossing angle in which a head side of the anchor 6 is directed to a descending direction with respect to a slide face of the unstable layer 2 of the board surface is formed to be 60° to 70°.SELECTED DRAWING: Figure 1
【課題】表層厚の浅い傾斜不安定地盤の地滑り防止を低コストで確実に行う、斜面安定化構造を提供する。【解決手段】傾斜地盤３の表層０．５ｍ以下の不安定層２の表面側にネット４を被覆し、該ネット４を多数のアンカー６により基盤に張設固定する斜面安定化構造であって、上記アンカー６を略正方形の頂点位置に配置するとともに、上記正方形の一方の対角線を不安定層２の滑り方向に沿わせることにより４本のアンカー６で囲まれるエリアを滑動単位１１として周辺エリアと縁切りし、前記各頂点間を３ｍ以下の滑動単位１１の幅Ｗ１，Ｗ２としており、基盤表面の不安定層２の滑り面に対し、アンカー６のヘッド側を下降方向に向けた対角が６０°〜７０°を形成させている。【選択図】図１
