DEFORMATIONAL BEHAVIOR OF SURROUNDING SOFT ROCK MASS IN TUNNELLING
Doboku Gakkai Ronbunshu, 1993 軟岩トンネルを掘削した場合の周辺岩盤の変形挙動を知るための理論解析について考察した. 岩盤の変形特性は軟化と残留を考慮したモデルとし, 強度特性はモール・クーロンの破壊基準に従うものとした. 岩盤物性値が変形挙動に及ぼす影響を調べた結果, 岩盤の強度特性が同じでも, それを構成する粘着力と内部摩擦角の組合せによって大きな違いがあることが明らかになった. また, 実際のトンネルの計測データと理論解を比較したところ, 岩盤の変形挙動を概ね説明しうることが分かった.
