The Experimental Study on Fracture Characteristic of Rock


Article Preview

Based on the stress analyses on the surrounding rockmass of underground caverns, the stress states on the surface and inside the surrounding rockmass are simulated respectively using biaxial compression tests and truly triaxial compression tests, and the fracture characteristic of rock and the relation between the angle of rock rupture,θ ,and stress state are studied. According to the testing results, the stress state condition of different type of rock bursts generating in different regions of the surrounding rockmass. The research results show that the rock burst of flake-splitting type takes place around the cavern’s surface under the biaxial compression stress state whereas that of shearing-dislocation type takes place inside the surrounding rockmass under the stress state of truly triaxial compression.
