英文摘要	Abstract Salt cavities used as underground gas storage have received increased attention for serviceability and sustainability considerations during gas cycling loading. However, traditional stability analysis overlooks the thermal effects induced by the operation and cannot predict the potential risk. In a field case in Jintan, Jiangsu Province of China, the thermal response to gas injection-and-withdrawal process of the walls of Cavern L was explored. A Bonded-Block Model (BBM) based on a 3DEC platform is proposed in inverse simulation for the field case’s cavity collapse process. By comparing the field case with simulation results, the proposed thermal-mechanical coupling model is validated for predicting the risk of cavity instability. The simulation results show that the thermal effect induces the collapse of the surrounding rock, that is, thermal tensile stress causes thermal cracks on the surface of the cavity.
