| 英文摘要 | Compressed air energy storage (CAES) is pivotal in integrating renewable energy and balancing the power grid. This study assesses the stability and ground subsidence of a proposed CAES salt cavern group in Jiangsu Province. A geomechanical model was established to simulate the operational conditions of the target cavern well group under pressures ranging from 16 to 18 MPa. The results indicate that, over the 30-year design lifespan, key indicators such as cavern deformation, plastic zone distribution, volume shrinkage and safety factor meet the long-term stability requirements. The ground subsidence of nine cavern well groups was analyzed, with the maximum subsidence after 30 years found to be 89.6 mm, and the coefficient of variation (CV) was <5 %. Using the proposed entropy weight-based method for identifying key subsidence-influencing caverns, the ANG1 well group was determined to be the critical influencing cavern. It is recommended to closely monitor the operational logs of the ANG1 well group and optimize the plant operation strategy based on actual conditions. Additionally, subsidence monitoring points should be added in the triangular area formed by the target well groups. This research provides a valuable reference for the construction of the CAES power station in Jiangsu Province. |
