A series of mechanics test on salt rock specimen took from the cretaceous stratum with buried depth of 2000 meters was carried out,including uniaxial and triaxial compression test,Brazilian tests,direct shear test.Based on the tested results,the uniaxial compressive strength,modulus of elasticity and triaxial compressive strength of the salt rock were studied,especially the effects of strata temperature and high confining pressure on mechanical properties of the salt rock were studied.The studies indicated that compared with salt rock from other regions at home and abroad,the uniaxial compressive strength and modulus of elasticity of the salt rock from Qianjiang is lower;temperature has significant influence on mechanical properties of the salt rock,the salt rock has very strong plastic deformation capability,the effect of confining pressure on its modulus of elasticity is very low;under high confining pressure there is obvious failure surface in the salt rock,it is no longer a simplex shear failure.The tensile strength and shear strength parameters of the salt rock from Qianjiang were studied,its tensile strength is 1.041 MPa,its cohesive strengthC=2.46 MPa,and its frictional angleφ=41.36°.
