Study on Engineering Behaviour of Schist Rock

Abstract

In the present world, many important rock structures are being planned, designed and constructed to meet the requirements of different civil and mining engineering applications. Knowing the various properties of the rock beforehand are requirement to assess the suitability of the rock for the particular application. Also, the strength of the rock is an important factor is effected to a significant extent due to the presence of joints and other defects in rock. Predicting the effect of joints on the strength of rock can help to large extent for making a better design of structure. Keeping in view of the above, the present study has been carried out to find out the different physical and mechanical properties of schist rocks so as to understand the suitable applications based on the properties obtained. The effect of joints in Schist rock is studied, empirical relationships are proposed for predicting the strength of the rock for a given joint geometry. Also, numerical modelling is done to analyze circular tunnels of different diameters under different insitu stress ratios made by using the results as obtained from the different experiments which have been carried out.
