Prevention of Large Deformation of Soft Surrounding Rock in Tunnel Construction
Journal of Measurements in Engineering, 2023 Large deformation of surrounding rock makes the internal space of a tunnel cannot meet the requirements of normal use after support, even leads to the instability of surrounding rock and destruction of the tunnel structure. In order to optimize the parameters of the primary support to control the deformation of surrounding rock, field tests and ...

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.
