Summary:PROBLEM TO BE SOLVED: To provide a tilt-restraining construction method for making an existing bridge pier directly built in the ground difficult to be tilted, by which construction can be operated safely at a low cost and the construction period can be shortened.SOLUTION: A tilt-restraining construction method is provided, for making an existing bridge pier 10 directly built in the ground difficult to be tilted, in which, when shaking of the ground occurs, the existing pier 10 is cut so that an upper part 21 above the cutting position and a lower part 22 below the cutting position relatively slide to each other.SELECTED DRAWING: Figure 3 【課題】地盤に直接設けられた既設橋脚を転倒しにくくする転倒抑制工法であって、安価で安全な施工が可能であり、かつ、工期の短縮化が可能な転倒抑制工法を提供する。【解決手段】地盤に直接設けられた既設橋脚１０を転倒しにくくする転倒抑制工法であって、地盤の揺れが発生した際、切断位置から上側の上側部分２１と切断位置から下側の下側部分２２とが相対的にスライドするように、既設橋脚１０を切断するように構成されている。【選択図】図３
