Basic Classification of Engineering Materials Basically Engineering Materials Can be classified into two categories- MetalsNon-Metals Metals Metals are polycrystalline bodies which are having number of differentially oriented fine crystals. Normally major metals are in solid states at normal temperature. However, some metals such as mercury are also in liquid state. Encompassing nearly all aspects of rock mass classifications in detail, Civil Engineering Rock Mass Classification: Tunnelling, Foundations and Landsides provides construction engineers and managers with extensive practical knowledge which is time-tested in the projects in Himalaya and other parts of the world in complex geological conditions.4/5(1). more importantly, of the principals of applied mechanics and structural engineering that should be the basis of tunnel support design. Fortunately, a few papers are now appearing that question the validity of designing using classification systems. A recent paper by File Size: KB.
A shear zone is a zone in which shearing has occurred so that the rock mass is crushed and brecciated. A shear zone is the outcome of a fault where the displacement is not confined to a single fracture, but is distributed through a fault zone.

Rock mass classification 5 Deere's RQD was widely used, particularly in North America, after its introduction. Cording and Deere (), Merritt () and Deere and Deere () attempted to relate RQD to Terzaghi's rock load factors and to rockbolt requirements in tunnels.
In the context of this discussion, the most important use of RQD is as a component of the RMR and Q.

Questions such as - Is Classification reasonably reliable. Can it be successful in crisis management of geohazards. Can a single Classification system be general for all rock structures.
Is Classification a scientific approach?5/5(3). Chapter One Philosophy of Engineering Classifications. When you can measure what you are speaking about, and express it in numbers, you know something about it, but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind; it may be the beginning of knowledge, but you have scarcely in your thoughts, advanced to the Pages: A comprehensive range of classification, or index, and engineering design tests have been carried out on the seven stages of weathering of rock material recognised in the Hingston Down granite from east Cornwall, England.
Interrelationships have been determined for all test results. It is concluded that the quick absorption, Schmidt hammer and point load strength tests are reliable and Cited by: Hoek-Brown rock mass strength parameters m, s, and O'c are suggested.
To incorporate the results of practical applications of the failure criterion under real engineering conditions, Hoek and Brown proposed equations to estimate rock mass strength pa rameters from. 1. ROCK CLASSIFICATIONS AND IT’S USE IN DESIGN Sourabh jain 1 2. INTRODUCTION • Rock mass classification systems are used for various engineering design and stability analysis.
• These are based on empirical relations between rock mass parameters and engineering applications, such as tunnels, slopes, foundations, and excavability. The above suggested engineering classifications are based on the measured/estimated engineering parameters of rock namely, σ ci, σ cj, E i, E j, J n, n, r, and also failure strains, and can be applied to both intact and jointed rocks.
However, in practice one may prefer to adopt strength and modulus directly for classifying a by: Z.

Written in EnglishCited by: Description and classification of soils and rocks INTRODUCTION From an engineering viewpoint, the ground beneath a site can conveniently be divided into the categories shown in Tablewhich are based upon generalizations of its expected behaviour in construction works.
These broad generalizations are, of course, limited in Size: KB. Slope mass rating (SMR) is a rock mass classification scheme developed by Manuel Romana to describe the strength of an individual rock outcrop or slope. The system is founded upon the more widely used RMR scheme, which is modified with quantitative guidelines to the rate the influence of adverse joint orientations (e.g.
joints dipping steeply out of the slope). Hadjigeorgiou J., Grenon M. and Lessard J.F. Defining in-situ block size. CIM Bulletin, 91(): 72— Heiner A.
