SEISMIC REINFORCEMENT METHOD FOR EXISTING MASONRY RETAINING WALL
To improve economic efficiency, construction period, and reinforcement effect, to enable design verification even for large-scale earthquakes, to improve initial construction cost and construction speed, and to reduce life cycle cost.SOLUTION: A seismic reinforcement method for an existing masonry retaining wall is adopted in which a covering concrete 7 having a thickness w that allows placement of reinforcing bars 7a is placed so as to cover a wall surface of the existing masonry retaining wall, a cross section of the retaining wall is formed by connecting a head of a tension bolt 1 to an extended section wh set on an upper surface of a back side of the covering concrete 7, and a head of a compression pile 2 to a lower end, and intervals B1 and B2 between the tension bolts 1 and the compression piles 2 in the extension direction of the retaining wall is set at a large pitch of 1.0 m to 2.5 m.SELECTED DRAWING: Figure 1
【課題】経済性と工期、及び、補強効果を改善すること、大規模地震に対しても設計照査が可能とすること、及び、初期工事費と施工速度の改善、更にライフサイクルコストを低減すること。【解決手段】既設石積み擁壁の壁面を覆うように鉄筋７ａの配置が可能な厚さｗの張りコンクリート７が配置され、その張りコンクリート７の上端側の背面側上面に設定した延長区間ｗｈに引張ボルト１の頭部が、下端側には圧縮杭２の頭部が連結された擁壁横断面から成り、引張ボルト１と圧縮杭２の擁壁延長方向打設間隔Ｂ１、Ｂ２は１．０ｍ～２．５ｍの大きなピッチとした既設石積み擁壁の耐震補強工法を採用した。【選択図】図１
