Abstract

Understanding the behavior of brittle rocks under different stress conditions is extremely important to the design and construction of underground projects such as mines, tunnels and underground hydropower stations. At the University of Hong Kong, both laboratory tests and numerical simulation were carried out to study the behavior of typical Hong Kong rocks. For the laboratory tests, the deformation properties (expressed by stress-strain curve) and failure process of granite under compression and tension were investigated. In addition, the evolution of dilatancy and time-dependent strength degradation of granite under constant loading were studied. AE technique was used to study the development of fracture during these tests. For the numerical simulations, the discrete element method was adopted to carry out numerical tests to simulate the laboratory tests. A same set of tests were carried out in the numerical simulations using the discrete element method (DEM). The present paper, which focuses on granite, reports and compares the results of the laboratory tests and the numerical simulations. © 2013 Taylor & Francis Group.
