Strength of jointed rock masses 2 Strength of jointed rock masses Evert Hoek, Golder Associates, Vancouver, Canada Synopsis Jointed rock masses comprise interlocking angular particles or blocks of hard brittle material separated by discontinuity surfaces which may or .   An assessment of the strength and deformational response of jointed rock masses is an essential requirement in the site selection, design and successful execution of Civil and Mining Engineering projects. A quick estimate of these properties for preliminary evaluation of alternate sites, will reduce considerable expenditures for field by: The mechanical behavior of rock masses is controlled by the presence of joints. Understanding the mechanical behavior of rock joints is essential to predict their influence on a rock mass.   The shear strength response is divided into two broad categories i.e. strength behaviour of joints and strength behaviour of jointed rock mass. Shear strength models described in this article cover linear as well as non-linear strength response. Classification systems are widely used to characterize the rock masses in the : Mahendra Singh.

2. Mechanical behavior of jointed rock mass. To investigate the mechanical characteristics of the jointed rock mass, associated experimental results are required. This study refers to artificial jointed rock mass, as performed by, and uses their experimental data for the base of the numerical simulations. The experimental setup and results are described as by: In this paper, the studies on elasto-plastic constitutive model for jointed rock mass are made. The influences of joints on the jointed rock mass are analyzed. Based on these studies, a constitutive model for jointed rock mass, which can consider anisotropic strength of jointed rock mass and anisotropic increase of plastic strain, is by: 5.   A strain-dependent strength and dilation model of rock to study pre-peak behaviour in confined tests; The reduction of surface settlement by employing umbrella arch systems for different excavation methods; Kinematic analysis of block rotations in a jointed rock mass; Vibration propagation in discrete element particle models of rock. Rock mass properties 9 the tunnel face is shown in Figure 3 and a back analysis of the behaviour of this material suggests that an appropriate value for V ci is approximately 50 MPa. In other words, on the scale of the m diameter tunnel, the rock mass properties are “averaged” and there.

The jointed rock mass possesses complex mechanical behaviors, the slip zones around circular openings on jointed rock masses has not been studied in detail from a theoretical point of view. Deformation behaviour of jointed rock mass is important to study if structures are being founded on rock-mass. Generally, the deformability of rock mass is represented by modulus of deformation. AN EXPERIMENTAL STUDY ON STRENGTH BEHAVIOUR OF JOINTED ROCK MASS THROUGH MODELLING UNDER UNIAXIAL COMPRESSION A PAPER SUBMITTED IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF Bachelor of Technology In Civil Engineering BY Under the Guidance of Prof. (Dr.) N. Roy Department of Civil Engineering National Institute of . Jointed rocks are typical examples of heterogeneous materials with joints. The existence of joints influences the physical properties of rock mass and propagation of fractures, which can affect.
