Prediction and Assessment of Lateral Displacement of Rock Mass Along the Length of the Horseshoe Cavern – A Numerical Modelling Approach
Abstract: The stability of the underground structures is a key to successful underground mining. Caverns are large underground openings constructed in rock mass for a variety of purposes. The properties of intact rock mass are generally overshadowed by the properties of discontinuities, if the discontinuities are present. Mechanisms of deformation and failure of underground openings in jointed rock mass are determined by the characteristics of the geometrical distribution of discontinuities. This …

Taguchis Parameter Design Approach to normal cement concrete mixture proportioning
Abstract: This paper presents the results of the optimization of normal cement concrete mixture using Taguchi approach. The Taguchi experiments were designed using an L9 orthogonal array with three factors and three levels each. The water-cement ratio (W/C), total aggregate-cement ratio (TA/C) and total aggregate-water ratio (TA/W) were treated as the control factors. The effects of the water-cement ratio, total aggregate-cement ratio and total aggregate-water ratio on the compressive strength were …

Solid Waste Management of Beta-1
Abstract: With rapid urbanization, the situation is becoming critical. The urban population has grown fivefold in the last six periods with 285.35 million people living in urban areas as per the 2001 census. Waste is littered all over leading to insanitary living conditions. Municipal laws overriding the urban local bodies do not have adequate provisions to deal effectively with the ever-growing problem of solid waste management. Solid waste management is one …

Effects of Reinforcing Elements in Soil Reinforcement
Abstract: The inclusion of reinforcing elements in a soil mass improves its geotechnical properties. The principle behind soil reinforcement is that the reinforcing elements absorb the tensile load and shear stress within the reinforced structures and hence prevent the shear failure and settlement. The friction developed between the interface of soil and reinforcing element improves the properties of soil. Different types of natural and synthetic fibers have been used in various …
