Abstract
This paper presents the analytical solutions and their numerical examples for the displacement caused by various loading on the inner surface of circular or elliptic hole in isotropic or anisotropic rock masses, to evaluate the loading tests in the pilot tunnel or borehole. The effects of loading width, Poisson's ratio, the ratio of maximum and minimum orthotropic elastic moduli of rock mass and the inclination angle of loading direction from their principal axes on the displacement was investigated, and then the evaluation procedure of elastic moduli by plate loading test was examined.
