| 英文摘要 | Salt caverns used for compressed air energy storage (CAES) undergo daily humidity cycling. The damaged surrounding rock contains extremely high deliquescent sodium chloride (NaCl) levels. This study used experimental and theoretical approaches to examine the dynamic deliquescence and salt transport behavior of damaged rock salt under humidity cycling. We uniaxially compressed rock salt to different damage levels and placed them in humidity cycles to measure their deliquescent mass losses. Ultrasonic pulse velocity (UPV) tests were used to investigate the internal integrity, while morphological changes on the surface of the rock salt were observed using vision and scanning electron microscopy (SEM). Based on these results, a dynamic salt transport mechanism coupled with ambient humidity was proposed, which was based on deliquescence and accounted for the diffusion, imbibition, and self-healing of rock salts. This mechanism explains the variation of deliquescence rate (DR) among rock salts at different damage levels. This helps in understanding the deliquescent effect of a humid CAES environment on the long-term volume change of the CAES cavern and the damage evolution of the surrounding rock. |
