摘要（英）：

The utility model discloses a rock damage space-time evolution testing system in a deep complex environment. The rock damage space-time evolution testing system comprises an acoustic emission sensor assembly and an acoustic emission amplifier assembly which are arranged on a rock mechanics testing machine, a three-axis cavity coupling bracket is arranged on the outer wall of the three-axis cavityand located between the two acoustic emission sensor assemblies. The triaxial cavity coupling bracket comprises a plate-shaped bracket, two sickle-shaped brackets and at least three bracket bolts, andcan be tightly hooped on the outer wall of the triaxial cavity; two guide columns are vertically fixed to the side face of the plate-shaped bracket, the acoustic emission amplifier assembly is installed between the two guide columns and above the plate-shaped bracket, and the acoustic emission amplifier assembly is connected with the acoustic emission sensor assembly through a signal line. The test system disclosed by the utility model solves the problems of acoustic emission signal interference and signal inaccuracy under the conditions of triaxial high temperature, high pressure, seepage and coupling thereof in the rock damage and damage test process at high temperature and high pressure.
