VACUUM CONSOLIDATION METHOD
PROBLEM TO BE SOLVED: To provide a construction method that enables a vacuum consolidation method to be economically executed on the ground in which such a layer with a relatively high coefficient of permeability as a peat layer exists on a surface layer.SOLUTION: In a vacuum consolidation method for ground improvement for ground having a surface layer comprising a layer with a water permeability coefficient of 10m/s or more, a low-permeability soil layer 20 with a water permeability coefficient of 1×10m/s or less and a cone bearing capacity of 400kN/mor more is formed on the surface layer. The low-permeability soil layer 20 is utilized as a negative pressure seal layer during vacuum consolidation.SELECTED DRAWING: Figure 1
【課題】泥炭層のような透水係数が比較的大きい層が表層に存在する地盤において真空圧密工法を経済的に実行可能な工法を提供する。【解決手段】表層に透水係数が10-5m/s以上の層を有する地盤に対する地盤改良のための真空圧密工法であって、透水係数が1×10-7m/s以下でコーン支持力が400kN/m2以上の低透水土層２０を表層上に形成し、低透水土層２０を真空圧密の際の負圧シール層として利用する。【選択図】図１
