EMBANKMENT STRUCTURE AND CONSTRUCTION METHOD OF EMBANKMENT STRUCTURE
To provide an embankment structure and a construction method of an embankment structure, which make effective use of a soft soil material having a high water content ratio or a high sensitivity ratio as an embankment material, and have excellent stability.SOLUTION: An embankment structure 1 is constructed by an embankment step in which high quality soil 5 is scattered and compacted to form an embankment layer 2, an excavation step of forming a band-shaped groove 3 in the embankment layer 2, an improved soil production step of mixing the soft soil, a solidifying material, and water to produce a slurry-type improved soil 4, and a filling step for filling the groove 3 with the improved soil 4.SELECTED DRAWING: Figure 1
【課題】含水比が高い、鋭敏比が大きい等の軟弱な土質材料を盛土材として有効に活用し、かつ、安定性に優れた盛土構造および盛土構造の施工方法を提供する。【解決手段】良質土５を撒き出すとともに締め固めて盛土層２を形成する盛土工程と、盛土層２に帯状の溝３を形成する掘削工程と、軟弱土と固化材と水とを混合してスラリー状の改良土４を製造する改良土製造工程と、溝３に改良土４を充填する充填工程とにより盛土構造１を施工する。【選択図】図１
