MODIFIED GROUND AND MODIFIER USED THEREFOR AND GROUND MODIFICATION METHOD
To provide a modified ground which is inexpensive, has a small burden on an environment and has a high ability to reduce liquefaction, and a modifier used therefor.SOLUTION: A modified ground 10 reduces liquefaction. The modified ground 10 includes target soil 11 and a modifying agent 12 added thereto. The target soil 11 is mainly composed of sediment particles 13 to be modified. The modifying agent 12 is mainly composed of waste paper fiber 14 and is added to the target soil 11. The waste paper fiber 14, which is the main component of the modifying agent 12 added to the target soil 11, exists in a complicated intertwined state between the sediment particles 13. As a result, when the pressure of pore water 15 existing between the sediment particles 13 increases, the excess pore water pressure is released through the waste paper fiber 14. As a result, liquefaction due to accumulation of excess pore water pressure is suppressed.SELECTED DRAWING: Figure 1
【課題】安価で環境への負荷が小さく、液状化を軽減する能力の高い改質地盤およびこれに用いる改質剤を提供する。【解決手段】改質地盤１０は、液状化を軽減する。改質地盤１０は、対象土壌１１とこれに添加される改質剤１２とを含んでいる。対象土壌１１は、改質の対象となる土砂の粒子１３を主成分としている。改質剤１２は、古紙繊維１４を主成分とし、対象土壌１１に添加される。対象土壌１１に添加される改質剤１２の主成分である古紙繊維１４は、土砂の粒子１３の間に複雑に絡み合って存在する。これにより、土砂の粒子１３の間に存在する間隙水１５の圧力が高まると、その過剰間隙水圧は古紙繊維１４を通して解放される。その結果、過剰間隙水圧の蓄積による液状化が抑制される。【選択図】図１
