Abstract：Regarding deep granodiorite(564–576 m) as the background，failure process of deep granodiorite and its acoustic emission(AE) characteristics were researched with microcomputer servo-controlled triaxial testing machine and AE monitoring system by conducting rock compression test and acoustic emission monitoring tests. By discussing the failure mechanism of granodiorite in uniaxial and triaxial compression，the regularity of various stages of AE in the process of rock failure was obtained and the envelope of crack initiation stress，crack connection stress and peak stress were obtained. Based on the test data，the relationship between AE parameters and rock failure was obtained and the preconditions for establishing engineering rock mass strength criterion were created.
