| 内容記述 | 本報告では沖縄の南風原村の1地点から採取した泥灰岩についての一軸圧縮強度を調べた。自然泥灰岩の一軸圧縮強度特性として次のことがわかった。1)泥灰岩円柱供試体の破壊形式はくさび形の破断面から破壊を起こす。2)一軸圧縮強度は17.40kg/(cm)^2から41.56kg/(cm)^2にまたがっている。3)自然泥灰岩の一軸圧縮強度は自然含水比によって変化し, 自然含水比の低いものほど強度は大きくなる。4)一軸圧縮強度と変形係数の間には一次関係を見い出すことはできないが, Fig.10に示すような傾向にある。5)自然泥灰岩を水浸すると強度が低下するが, 自然含水比の低いものほど強度の低下が著しい。これは自然含水比の低いものほど水浸すると吸水膨張を起こし, 乾燥密度が低下するからである。 | |||||||||
