Excerpt

Stability and deformation analysis for geotechnical projects like tunnels, underground openings and rock slopes or reservoir engineering problems need reliable data about the behaviour of discontinuities (joints, fractures, bedding planes etc.). Especially, the tremendous progress in numerical simulation techniques require detailed data about deformation, strength and damage characteristics of geomaterials. Shear box tests are widely used in geotechnical engineering to obtain soil mechanical data. Shear box devices for rockmechanical testing are also common, but, by far, not in the same capacity. This is mainly due to the fact that rockmechanical testing equipment, in general, needs much higher forces, higher resolution in deformation measurements and larger specimens. This makes the equipment much more expensive, bigger in size and more complicated in handling. Today, commercial shear box devices for rockmechanical testing are restricted to maximum forces of between 200 and 500 kN and restricted to pure quasi-static mechanical testing (e.g. MTS-816.01, GCTS-RDS-300 or TerraTek-DS-4250). Also, most of the latest published in-house developments have reported maximum forces of about 500 kN, pure mechanical loading and no dynamics [e.g. Gomez (2008); Geertsma (2002); Balthasar et al. (2006); Kim et al. (2006); Jiang et al. (2004); Seidel and Haberfield (2002); Wong et al. (2007)]. Superimposed dynamic testing and/or hydro-mechanical coupled testing was reported by Buzzi et al. (2008) and Barla et al. (2007, 2010), but on significantly smaller samples and devices of quite different types. To investigate higher stress environments at up to about 5,000 m in depth or larger samples at lower stress levels, higher forces are necessary. …
