Scale-Model Experiment on the Delayed Failure Mechanism of Deep Tunnels in Brittle Rock

Rock bursts usually happen during the hours or days after tunnel excavation, even in an unsupported opening where no collapses occur. To investigate the mechanism of those delayed failures in brittle rock tunnels, this paper showcases the performed scale-model test based upon the Jinping II headrace...
