When a tunnel or an underground structure is excavated in a highly stressed rock mass, rock damaged zone is formed around the tunnel due to the stress concentration resulting from stress redistribution. Recent studies on the rock damaged zone revealed its importance to structural stability around deep underground openings. In order to evaluate the characteristics of the rock damaged zone by brittle failure, physical model test and numerical model tests have been conducted. For this study, a new… CONTINUE READING
