Sažetak
This study proposes a multi-scale damage correlation path to characterise the softening behaviour of soft rock under dry-wet cycles, based on multi-scale damage variables. By testing the mineral composition and internal structural changes of soft rocks under different dry-wet cycles, and based on the energy evolution mechanism and damage constitutive characteristics, the multi-scale correlation effects of soft rock softening under dry-wet cycles were analysed. The results indicate that as the number of dry-wet cycles increase, the mechanical properties of soft rock exhibit an exponential decay mode, and mineral particles exhibit Weibull-distributed random failure behaviour.
