In Situ Stress Paths Applied in Rock Strength Characterisation Result in a More Correct and Sustainable Design
Andre Vervoort
Abstract:Rock strength is an essential parameter in the design of any underground excavation, and it has become even more relevant as the focus increasingly shifts to sustainable excavations. The heterogeneous nature of rock material makes characterising the strength of rocks a difficult and challenging task. The research results presented in this article compare the impact on the strength when the classic stress paths in laboratory experiments are applied versus when in situ stress paths would be applied. In most labo… Show more
