PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure structure, which can be easily constructed and curb inclination and settlement of a structure.SOLUTION: A liquefaction countermeasure structure 1A for a structure 12 constructed in natural ground 11 subject to liquefaction, comprises: a ground improvement body 2A constructed below a foundation section 15 of the structure 12; and a gravel layer section 3A which is constructed by laying a gravel material on at least a portion of a lateral side and a lower side among an entire peripheral section 15A of the foundation section 15, and has a drainage function with a larger coefficient of permeability than the natural ground 11. The gravel layer section 3A is connected to an outer periphery of the foundation section 15 and a lower face of the peripheral section 15A, as well as an upper side of the ground improvement body 2A.SELECTED DRAWING: Figure 2
【課題】施工が容易で、構造物の傾斜や沈下を抑制することができる液状化対策構造を提供する。【解決手段】液状化地盤である原地盤11に構築された構造物12の液状化対策構造1Aにおいて、構造物12の基礎部15の下方に形成された地盤改良体2Aと、基礎部15の外周部15A全体のうちの少なくとも一部の側方および下方のそれぞれに礫材が敷設されることで形成され原地盤11よりも透水係数が大きい排水機能を有する礫層部3Aと、を有し、礫層部3Aは、基礎部15の外周面および外周部15Aの下面と接続されているとともに地盤改良体2Aの上部側と接続されている。【選択図】図2
