... in this paper. Research analyzes the uniaxial compressive strength influenced by moisture content, the triaxial compressive strength and the elasticity modulus influenced by confining stress. Moreover the optimal correlativity of the compressive and elasticity modulus is obtained through analyzing the curve...
