2K6CE 705(C) REINFORCED EARTH AND GEOTEXTILES

MODULE I (13 hours)
Necessity of soil improvement – selection of improvement method, Earth reinforcement – mechanism and concept, tress- strain relationship of reinforced soil, Design theories and stability analysis of retaining wall – tie backanalysis – coherent gravity analysis.
MODULE II (13 hours)
Concepts of soil reinforcement principles, materials of reinforcement, type of metals, geotextiles, synthetics, natural fibres, type and positioning of reinforcement facing, Application of reinforced earth, construction methods, Estimation of pressure on reinforcement, Design of reinforced earth retaining wall using metallic reinforcement.
MODULE III (13 hours) 
Development of geotextiles, types of geotextiles and related products, geosynthetics, woven and nonwoven geocomposites, properties, functions – relations between functions and properties, Tests and specifications – influence of soil properties on test results, Application of geotextiles for erosion control, filter, foundation, retaining walls.
MODULE IV (13 hours)
Simple examples of uses and application of geotextiles for soil stabilization, use of geotextiles and geocomposites for retaining walls, embankment, slopes, foundation pavements, filters – construction details are to be indicated with examples – field application in India, Design of only geotextile or geogrid retaing walls are to be expected.
