Available in PDF, EPUB and Kindle. Book excerpt: Several massive, complicated and difficult to design structure are under construction or planning stages under very complex geological condition in India and around the world. Even small variation in appraisal and design can cost millions. Hence initial development of understanding under control condition is very important and desirable for characteristic and prediction of behavior. It is essential to have a clear understanding of strength and deformation behavior of jointed mass for realistic analysis and rational designing of engineering structure .The most important factors which govern the strength of rock mass type are type of rocks, bedding planes, stress condition, presence of cracks and fissures and nature of joint surfaces, presence of minerals in bedding planes also play an important role in the strength and deformation behavior of jointed rock mass. As the in situ determinations of jointed rock mass is costly and time consuming attempts are being made to predict the strength and deformation of rock mass through model test under controlled laboratory conditions Considering the importance of this study the experimental study has been under taken to determine the strength and deformation behavior of jointed rock mass. Models will be prepared using Plaster of paris, cement mad mica and different degrees of anisotropy have been induced by making joints in them varying from 0 to 90 degree. The specimen will be tested under direct shear, uniaxial compression to determine the various parameters.

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Stability analysis of a rock mass is an important and complicated problem related to the safety of engineering buildings. One of the major tasks of engineering geomechanics is to evaluate the rock mass stability both qualitatively and quantitatively. The ultimate strength and deformation of jointed rock mass are important parameters that designers look for in selecting sites for foundations of civil structures in rocks. In nature rock is exists as a rock mass. It is a discontinuous medium with fissures, fractures, joints, bedding planes, and faults. These discontinuities may exist with or without gouge material. The strength of rock masses depends on the behaviour of these discontinuities or planes of weakness. The frequency of joints, their orientation with respect to the engineering structures, and the roughness of the joint have a significant importance from the stability point of view. Reliable characterization of the strength and deformation behaviour of jointed rocks is very important for safe design of various types of civil structures such as arch dams, bridge piers, and tunnels.

Book excerpt: Most rock masses encountered in civil and mining engineering projects contain pre-existing discontinuities. These discontinuities weaken the rock masses to an extent, which depends very much on the size of engineering structure relation to discontinuity spacing. The strength and deformability of rock mass is controlled not only by the intact portion of rock, but by the characteristic of the joints that break up the mass, particularly their pattern and their orientation with respect to the in-situ stresses. In considering the effect of joints, the discrete approach emerged as an efficient tool and advocated since 1970s (Cundall, 1971). However, the numerical approach with modelling the joints explicitly has the limitation of computational complexity for modelling large-scale problems with extremely large number of joints. As an alternative to this limitation, the equivalent continuum approach models the jointed rock masses as a continuum with the equivalent properties that represent implicitly the effects of the joints. Several numerical methods have been developed by various researchers to model jointed rock masses as equivalent continuum, using various techniques. However, the existing equivalent continuum models are complicated and need more input data from experimental or field testing in order to carry out the analysis. Present approach attempts to use statistical relations, which are simple and obtained after analyzing a large data from the literature on laboratory test results of jointed rock masses. Systematic investigations were done including laboratory experiments to develop the methodologies to determine the equivalent material properties of rock mass and their stress-strain behaviour, using a hyperbolic approach (Duncan and Chang, 1970). Present study covers the development of equivalent continuum model for rock mass right from developing statistical correlations to find out equivalent material properties based on experimental results, to the implementat.
