ABUTMENT REINFORCEMENT STRUCTURE AND REINFORCING METHOD
PROBLEM TO BE SOLVED: To provide an abutment reinforcement structure capable of reducing earth pressure applied on an abutment in earthquake, obtaining excellent earthquake resistance and reducing construction cost due to a simple reinforcement structure.SOLUTION: An abutment reinforcement structure comprises: multiple large-diameter reinforcement anchors 10, which are substantially horizontally disposed with a predetermined distance therebetween on a surface side continuing to a lateral face 1b of an abutment 1 of a banking S positioned on a rear face 1a side of the abutment 1, in substantially parallel with the rear face 1a of the abutment 1; multiple concrete anchors 20, which are disposed with a predetermined distance therebetween on the lateral face 1b of the abutment 1; and a connection wall 30, which integrally connects the multiple large-diameter reinforcement anchors 10 and the multiple concrete anchors 20.SELECTED DRAWING: Figure 1
【課題】地震時における橋台が受ける土圧を小さくすることができ、優れた耐震性が得られるうえ、簡単な補強構造となるので施工にかかるコストの低減を図ることができる。【解決手段】橋台１の背面１ａ側に位置する盛土Ｓのうち、その橋台１の側面１ｂと連続するように形成されている面側に、互いに所定の間隔を保って設けられるとともに、その橋台１の背面１ａと略平行し、かつ、略水平となるように設けられた複数の大径補強アンカー１０と、橋台１の側面１ｂ側に互いに所定の間隔を保って設けられた複数のコンクリートアンカー２０と、複数の大径補強アンカー１０及び複数のコンクリートアンカー２０を一体的に接続する連結壁３０とからなる構成の橋台の補強構造を提供する。【選択図】図１
