When designing construction in rock foundation, measurement of natural state of stress in rock mass is an important problem. The state of stress of rock foundation is defined by gravitational and tectonic force fields. The gravitational force field can not be separated from the rock materials. At any point in an elastic homogeneous isotropic rock mass gravitational components of stress field are defined by the formulas:
