Experimental study on mechanical property of rock salt with impurity
Abstract：Mechanical experiments were carried out on the different kinds of rock samples which are salt,mudstone,glauberite,anhydrite and salt-mudstone.The experiment results indicate that different impurities have obvious effect on the deformability and the compressive strength;The modulus of elasticity and the uniaxial strength have a large range with the kind and content of the impurities and the glauberite＇s are higher;In triaxial compression tests,pure rock salts have a higher internal friction angle and a lower cohesion than the rocks with impurities.Besides the rock salt,the internal friction angle and cohesion of anhydrite are lower than others＇.The test results provide certain reference to the design of salt cavern under complex stratum.
