ABSTRACT
Salt rock which exhibits unique features such as leak
tightness, creep behaviour, low permeability and
damage self-healing, is used as ideal sealing medium
for underground energy reserves (such as oil, natural
gas) and waste disposal (such as nuclear waste, car-
bon dioxide). A series of experimental and theoreti-
cal studies on mechanical properties of salt rock
were carried out by many researchers, such as
Skrotzki (2009), Hunsche et al. (1990, 1999), Crist-
escu et al. (1998), Chan et al. (1998), Hou et al.
(2002, 2003), Yang et al. (2009), Zhou et al. (2009)
and etc, the relevant mechanical parameters were
obtained, and the corresponding constitutive me-
chanical models were further established.
