Abstract:In order to get the energy dissipation characters of Three Gorges granite under different loading modes,the complete procedure experiments of 3-point binding,Brazilian tension,uniaxial compression and triaxial compression are conducted with servo-controlled testing machines MTS and RMT. The energy dissipation of specimen under these 4 kinds of loading mode is calculated. According to experimental results,a 3-point bending specimen dissipates minimum energy,a Brazilian tension specimen dissipates much more energy than a 3-point bending specimen,and less than a uniaxial compression specimen,and a triaxial compression specimen dissipates maximum energy.
