Abstract In order to clarify the influence mechanism of excavation disturbance and large-equivalent explosion ground impact disturbance on the damage of deeply buried caverns，a similar model test incorporating the whole process of ground stress loading，cavern excavation and ground impact disturbance loading was carried out using the self-developed ground impact effect simulation test system for deeply buried caverns. The tests successfully simulated ground impact disturbance-induced engineering disasters at a burial depth of 600 m，a confinement blast equivalent of 90 kt and a proportional blast distance of 133 m/kt1/3. During the test，the phenomena of particle ejection，plate cracking and block activation were simulated successfully. The changes of stress，strain and displacement around the cavern and the failure mechanism of the deep cavern under the impact disturbance were obtained. It is confirmed that the cavern is in the zone of slight damage when the proportional blast distance is 133 m/kt1/3. In addition，a research on the stability of the cavern under repeated ground impact disturbance was carried out. Engineering disasters such as rock burst，slab crack and face collapse were simulated successfully，and the failure mechanism of the cavern under repeated impact disturbance was obtained. The successful conduct of the tests has laid an important foundation for the determination of protection and safety limits for deeply buried caverns under the action of large yielding underground explosions.

Key words： rock mechanics deep buried caverns ground impact failure similar simulation tests irreversible displacement large-equivalent explosions
