SEISMIC REINFORCEMENT STRUCTURE FOR EARTHEN EMBANKMENT
PROBLEM TO BE SOLVED: To provide a seismic reinforcement structure for an earthen embankment that suppresses amount of steel sheet piles used and reduce construction costs.SOLUTION: A seismic reinforcement structure 1 for an earthen embankment of the present invention is a seismic reinforcement structure for an earthen embankment 5 formed on a foundation part 3 having a liquefaction layer 13 above a bearing layer 11, and includes a plurality of cylindrical skeleton body 9 formed continuously along an axial direction of the earthen embankment 5, adjacent to each other, the cylindrical skeleton body being made by installing on the earthen embankment 5 a plurality of linear steel sheet piles 7 in a cylindrical form by connecting a joint 7a thereof, with a bottom edge part of all the linear steel sheet piles 7 embedded in the liquefaction layer 13.SELECTED DRAWING: Figure 1
【課題】鋼矢板の使用量を抑えることができ、施工コストを縮減することができる土堤の耐震補強構造を提供する。【解決手段】本発明に係る土堤の耐震補強構造１は、支持層１１の上方が液状化層１３になっている基盤部３上に形成された土堤５の耐震補強構造であって、複数の直線形鋼矢板７を、その継手部７ａを連結させて円筒状で、かつ全ての直線形鋼矢板７の下端部が液状化層１３内に位置しているように土堤５に打設してなる円筒骨格体９を、土堤５の軸線方向に隣接させて連続して形成したことを特徴とするものである。【選択図】 図１
