... ABSTRACT: In jointed rock masses deformability is associated with the mechanical properties of the intact rock and the rock joints. It is also known that the deformation modulus of jointed rock masses is anisotropic because of the presence of rock joints. This paper presents an analytical...

... ABSTRACT: A Homogenized Multi-Crack Model is proposed in order to estimate the deformability of a rock mass which has a high crack density. In this model, all cracks are parallel and infinitely arranged at equal intervals in all directions, and the crack pattern around a crack is always...

... ABSTACT: The evaluation of the elastic constants contained in the deformability matrix using diametral compression tests has been the main subject of some papers presented in the ISRM Congresses. In this work, new expressions are proposed for the determination of elements of the deformability...

.... In this paper, rock masses are regarded as cross-anisotropic materials. Deformability of rock masses Deformability of rock masses is assumed as follows: Modulus of deformation (E 1 )and Poisson's ratio (V 1 ) in the bedding plane, and modulus of deformation (E 2 )in the orientation perpendiculared...
