Because of it slow permeability and excellent creep behavior,
salt rock can ensure a good seal in storage caverns.In addition,salt
rock has stable mechanical properties and the capacity of self-repair
;hence,salt rock caverns are recognized as ideal storage
places for gas and oil.The fatigue characteristics of salt rock play
an importantroleinthelong-termstabilityofsaltcaverns.For
energy engineering,understanding the fatigue behavior of salt
rock caverns is essential for ensuring safe and stable operation of
storage caverns.
