To provide a sample preparation method capable of preparing a uniform sample by appropriately removing air bubbles from solidified soil using cement-based solidifying material.SOLUTION: The sample preparation method includes: putting solidified soil, which is a mixture of sample soil and cement-based solidifying material, into a tubular container; placing the tubular container containing the solidified soil on the table of the table vibrator; and subjecting the tubular container to vibration for 5 seconds or more with a vibration frequency of 40 Hz or more and 90 Hz or less, and amplitude of 0.75±0.05 mm in the vertical direction, depending on the condition of the solidified soil.SELECTED DRAWING: Figure 3
【課題】セメント系固化材を用いた固化処理土から気泡等を適切に除去して均一な供試体を作製できる供試体作製方法を提供すること。【解決手段】試料土とセメント系固化材とが混合された固化処理土を筒状容器に投入した後、固化処理土が投入された筒状容器をテーブルバイブレータのテーブル上に載置して、テーブルを固化処理土の状態に応じて例えば４０Ｈｚ以上９０Ｈｚ以下の振動周波数、鉛直方向に０．７５ｍｍ±０．０５ｍｍの振幅で５秒以上振動させて供試体を作製する。【選択図】図３
