英文摘要: Understanding the failure mechanism of bedded salt formations surrounding salt caverns is of great importance for underground gas storage. However, laboratory mechanical experiments of cores alone are insufficient to determine the mechanical properties of bedded salt formations, because the stress state of the cores varies spatially, and man-made damage might have occurred during the coring process, especially at the interfaces. Therefore, both physical simulation experiments and numerical analyses are needed to better understand the failure mechanism of bedded salt formations surrounding salt caverns. According to the physical simulation tests, the uniaxial and triaxial compressive strength curves of bedded salt rocks appear to be U-shaped as the dip angle changes, implying that shear...
