These phenomena can to some extent be explained quantitatively applying the dimensional analysis (Fig. 3,4 and Eq.(2)) . Settlement versus time elapse relationship for a compacted soil is that the degree of immediate settlement is large. This is represented by two curves, which are due to the immediate settlement and the consolidation settlement, using a numerical calucuration method(Fig. 5,6). Besides, distribution of the pore pressure during the consolidation test was measured by a small pressure meter which was placed at the center of the specimen. As compared with the values calculated by Terzaghi's one dimensional theory of consolidation, the primary consolidation settlement for a compacted soil was found to be the validity of Terzaghi's theory on the saturated soil (Fig.7,8,9 and Eq.(11))., 本論文は大型圧密試験機(リングの大きさ 直径30cm, 高さ10cm)を用いて締固め土の圧密特性を調べたものである。大型試験機と標準試験機の試験値を比較した結果, 体積圧縮係数は両者の間に大きな差異は認められなかったが圧密係数については大型試験機の方が標準試験機よりもかなり大きな値が得られた。そして, このような傾向が次元解析によって定量的に説明できることを示した。また, 締固め土の圧密沈下量~時間関係において大型試験ではとくに即時沈下部分が大きな割合を占めることが特徴的である。数値計算法を用いてこの圧密沈下量~時間関係を即時沈下と圧密沈下の二つの曲線で表示したところ, 計算値は比較的良好に実験値を近似し得ることが明らかとなった。一方, 供試体中に埋設した小型間隙圧計によって圧密中の間隙圧発生値を測定し, 測定間隙圧値をテルツァギーの一次元圧密理論で計算される値と比較した結果, 締固め土でも圧密沈下部分は飽和土理論に従うとみなしてもよいことを示した。}, pages = {51--62}, title = {Consolidation Behaviors of Compacted Soils Using a Large Scale Oedometer}, volume = {1}, year = {1988} }
