BANKING STRUCTURE AND METHOD FOR FORMING BANKING STRUCTURE
To suppress settlement of a structure at the time of liquefaction phenomenon occurrence, for a foundation of a banking structure including foam resin blocks.SOLUTION: A banking structure (10) is provided in a support ground (S) including a liquefaction layer (12), and includes at least two sheet pile walls (21, 22), a surface layer part (4), and a banking structure (1) including foam resin blocks (1a), wherein the two sheet pile walls (21, 22) are embedded in the liquefaction layer (12) so that the sheet pile walls face each other, the surface layer part (4) includes a ground improvement layer (4a), and is formed on the surface layer of the support ground (S) between the two sheet pile walls (21, 22), and the banking structure (1) is provided right above the ground improvement layer (4a).SELECTED DRAWING: Figure 1
【課題】発泡樹脂ブロックを含む盛土構造の基礎に対して、液状化現象発生時の構造物の沈下を抑制する。【解決手段】盛土構造体（１０）は、液状化層（１２）を含む支持地盤（Ｓ）に設けられ、少なくとも２つの矢板壁（２１、２２）と、表層部（４）と、発泡樹脂ブロック（１ａ）を含む盛土構造（１）と、を備え、２つの矢板壁（２１、２２）は、液状化層（１２）中に互いに対向するように埋設されており、表層部（４）は、地盤改良層（４ａ）を含むとともに、２つの矢板壁（２１、２２）間の支持地盤（Ｓ）の表層に形成されており、盛土構造（１）は、地盤改良層（４ａ）の真上に設けられている。【選択図】図１
