STRUCTURE AND METHOD FOR REINFORCING ABUTMENT
PROBLEM TO BE SOLVED: To provide a reinforcement structure capable of reducing earth pressure applied to an abutment during earthquakes and capable of obtaining excellent earthquake resistance, and a reinforcement method for the same.SOLUTION: In a structure for reinforcing an abutment, a fill improvement body 10 made of a plurality of columnar bodies is vertically provided in fill S that is positioned on the side of a back surface 1a of the abutment 1. The plurality of fill improvement bodies 10 are arranged like a wavy line formed of a linear line, in the state of being connected like a wall in such a manner as to adjoin each other in a direction crossing a bridge axis direction X along an extension direction of a bridge B in a plan view.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補強構造及びその補強方法を提供する。【解決手段】橋台１の背面１ａ側に位置する盛土Ｓ中に複数の柱状体からなる盛土改良体１０を鉛直方向に設けた橋台の補強構造であって、複数の盛土改良体１０は、平面視で橋Ｂの延在方向に沿う橋軸方向Ｘに対して交差する方向に隣接させて壁状に連結させた状態で、直線で形成される波線状に配列された構成の橋台の補強構造。【選択図】図１
