Summary:To provide a ground improvement method allowing uniform mixing of hydraulic powder being a solidification material into soil containing clay.SOLUTION: In a ground improvement method, hydraulic powder (A) and water insoluble solid particles (B) (excluding the (A)) with a grain fineness number AFS of 20 or more and 100 or less are mixed with soil containing clay. The hydraulic powder (A) is powder hardened by a hydration reaction, for example, cement and gypsum.SELECTED DRAWING: Figure 1 【課題】粘土を含む土壌に、固化材である水硬性粉体を均一に混合できる地盤改良工法を提供する。【解決手段】粘土を含む土壌に、（Ａ）水硬性粉体と（Ｂ）粒度指数ＡＦＳが２０以上１００以下である水不溶性固体粒子〔（Ａ）を除く〕とを混合する、地盤改良工法。（Ａ）成分の水硬性粉体は、水和反応により硬化する粉体のことであり、セメント、石膏等があげられる【選択図】図１
