Sound emission probe mounting device for true triaxial hydraulic fracturing simulation experiment

The invention provides a sound emission probe mounting device for a true triaxial hydraulic fracturing simulation experiment, and relates to triaxial fracturing initiation and expansion law physical simulation experiment technology. The sound emission probe mounting device for the true triaxial hydraulic fracturing simulation experiment comprises a bearing plate mounted in a pressure chamber, at least one mounting hole is formed in the bearing plate and used for mounting a sound emission probe, and a wiring groove is formed in the bearing plate and used for mounting a lead for connecting the sound emission probe with an amplifier. As the sound emission probe is mounted on the bearing plate mounted in the pressure chamber, the path of transmitting a sound emission signal generated by a rock sample to the sound emission probe can be shortened, the sound emission probe can be protected from damage in the process of a high-load experiment by the aid of a three-level counter bore structure, and accuracy and reliability of triaxial fracturing experiment results can be improved.
