Abstract To investigate the nonlinear response of deep bedded salt cavern(group) subjected to extreme loads，the numerical model considering the complete process of water solution，cyclic operation，and internal pressure runaway was established according to the geological structure of Jintan deposit. The effects of rapid unloading on the progressive failure，the volume convergence of single and double cavern，as well as the surface subsidence were calculated utilizing a new elasto-viscoplastic damage model for rock salt. The results reveal that the damage and failure region extends much deeper in the mudstone than that in the host salt. The damage and failure volume of surrounding salt induced by unloading process is 5–10 times larger than that of 10-year cyclic injection- ejection. The average volume convergence rate of salt cavern reaches 0.012%/d–0.013%/d. It is 6.0–6.5 times faster than that caused by cyclic operation. The surface subsidence presents a typical funnel curve. The influenced range of surface subsidence due to rapid unloading is about two times the maximum cavern diameters. The double cavern analysis indicates that the interaction between adjacent caverns is not obvious given the pillar width is larger than two times the maximum cavern diameters.

Key words： rock mechanics bedded rock salt gas storage creep damage uncontrolled unloading stability
