EARTH RETAINING WALL REINFORCEMENT STRUCTURE
To provide an earth retaining wall reinforcement structure easy to be constructed and allowing reduction of side flow pressure on the earth retaining wall upon liquefaction.SOLUTION: An earth retaining wall reinforcement structure is provided with a steel wall (wall body) 11 embedded in a rear earth wherein the steel wall 11 is provided with: an earth pressure reducing wall 12 installed generally parallel to an extending direction of the earth retaining wall 10; and a resistance wall 15 connected to the earth pressure reducing wall 12 and generally orthogonal to the earth pressure reducing wall 12 as well as extending in a direction opposite to the earth retaining wall 10. As the earth pressure reducing wall 12 is not connected to the earth retaining wall 10 and a lower end part of the resistance wall 15 is anchored into a non-liquefied layer NLL, the construction is easily performed and side flow pressure acting on the earth retaining wall 10 can be reduced upon liquefaction.SELECTED DRAWING: Figure 1
【課題】施工が容易であるとともに、液状化時において、土留壁に作用する側方流動圧の低減を図ることができる土留壁補強構造を提供する。【解決手段】土留壁補強構造は、背面土に埋設される鋼製壁（壁体）１１を備え、鋼製壁１１が土留壁１０の延在方向と略平行に設けられた土圧低減壁１２と、土圧低減壁１２に連結されるとともに土圧低減壁１２と略直交し、かつ土留壁１０と逆側に延在する抵抗壁１５とを備え、土圧低減壁１２は土留壁１０に連結されておらず、抵抗壁１５の下端部は非液状化層ＮＬＬに根入れされているので、施工が容易であるとともに、液状化時において、土留壁１０に作用する側方流動圧の低減を図ることができる【選択図】図１
