Practical Rock Engineering Chapter 11 Rock Mass Properties Pdf The following examples are presented in order to illustrate the range of rock mass properties that can be encountered in the field and to give the reader some insight of how the estimation of rock mass properties was tackled in a number of actual projects. Engineering rock mass classification ign, in particular for determining support requirements. while the classification schemes are appropriate for their original application, especially if used within the bounds of the case histories from which they were developed, considerable caution must be exercised in applying rock.
Geotek 05 Rock Mass Properties Classification Estimation Pdf Properties of rock mass therefore are governed by the parameters of rock joints and rock material, as well as boundary conditions, as listed in table 6.1.1a. Several textbook describe formation, development and composition of rocks as well as rock properties, among others lama and vutukuri (1976), see publication references. Rock mass is a matrix consisting of rock material and rock discontinuities. its characterization and classification aim to determine the rock mass characteristics by assigning values to a set of rock parameters. This document discusses the hoek brown failure criterion for estimating the strength and deformation properties of rock masses. it provides details on: 1) estimating the intact rock strength (ciσ) and hoek brown constant (mi) from triaxial test data on rock cores.
Rock Mass Classification System Pdf Structural Geology Strength Rock mass is a matrix consisting of rock material and rock discontinuities. its characterization and classification aim to determine the rock mass characteristics by assigning values to a set of rock parameters. This document discusses the hoek brown failure criterion for estimating the strength and deformation properties of rock masses. it provides details on: 1) estimating the intact rock strength (ciσ) and hoek brown constant (mi) from triaxial test data on rock cores. Rock mass characterization refers to the integrated assessment of various parameters that describe the properties of jointed rock masses, taking into account factors such as geology, rock material, and the influence of joints on rock properties. Rock masses can be considered to be a function of a number of measurable parameters, with respect to their geomechanical properties display in massive and actual form. In general, compared to intact rock, a rock mass has reduced tensile strength (almost zero), and reduced shear strength especially along discontinuity planes. furthermore, if a rock mass is cut by directional joint sets, the rock mass strength is anisotropic. Course notes on rock mass classifications, properties, and engineering applications. university level material for geotechnical engineers.
