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