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.
