ESTIMATING DEFORMATION MODULUS OF ROCK MASS FROM BIENIAWSKI'S ROCK MASS RATING (RMR)
Doboku Gakkai Ronbunshu, 2000 本文では, Bieniawski の岩盤分類評価法RMRから岩盤の変形係数を推定する方法を新たに提案する. 提案方法は, Hoek-Brown の岩盤破壊基準を基に, 岩盤の限界ひずみと岩石の限界ひずみとがほぼ等しいという条件から導出したものである. 日本国内の平板載荷試験の結果と比較することにより, 提案方法が既存方法より改善された推定結果を与えることを示す.

Bayesian prediction of TBM penetration rate in rock mass
Engineering Geology, 2017 Abstract One of the essential tasks in the excavation of tunnels with TBM is the reliable estimation of its performance needed for the planning, cost control and other decision making on the feasibility of the tunneling project. The current study aims at predicting the rate of penetration (RoP) of TBM on the basis of the rock mass parameters ...
