The rock salts from Yingcheng mine of Hubei Province and Jintan mine of Jiangsu Province were studied through uniaxial compression，triaxial compression and Brazilian tests. The properties of short-term strength and deformation of the two rock salts were analyzed. The experimental results indicated that the rock salts from two different places exhibit similar mechanical behaviors though there are some quantitative discrepancies. The failure of two kinds of rock salts can be described well by Mohr-Coulomb failure criteria. The results also indicated that the rock salts have considerable plastic deformation capability and dilatant deformation capability；and the rocks behave obvious strain hardening characteristic under high confining pressure. The presented results can be expected to provide useful references to the stability analysis of rock salt in underground engineering and the site selection of energy storage in rock salts.
