This paper presents a method which determines the elastic properties of anisotropic rock masses by interpreting the response of the various loading against the inner-surface of tunnel. Recently, the evaluation of rock mass properties has been tried to use the displacement data by gripper loads at TBM tunnelling. This method can be applied for their data. In the first, the mathematical formulation is given, and then the numerical calculations are presented for several loading conditions.
