On the basis of anisotropy of mechanical property of rock mass and based on the orthogonal anisotropy elastic theory of rock mass,this treatise has advanced the principle measuring magnitudes and directions of two horizontal principal stresses by hydraulic fracturing method and the method measuring and calculating elastic parameters of rock mass relating to the stress measurement in rock mass.
