SF4012 Geosynthetics and Reinforced Soil Structures Syllabus:
SF4012 Geosynthetics and Reinforced Soil Structures Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVES:
To understand the mechanism of the reinforcement, its influence in the shear strength and design concept for various applications in geotechnical engineering.
UNIT I PRINCIPLES AND MECHANISMS OF SOIL REINFORCEMENT
Historical Background – Principles – Concepts and Mechanisms of reinforced earth – Soil – Geosynthetics interaction mechanism – interface resistance – Factors influencing interaction – Strain compatability.
UNIT II REINFORCING MATERIALS AND THEIR PROPERTIES
Materials used in reinforced soil structures, fill materials, reinforcing materials metal strips, Geotextile, Geogrids, Geomembranes, Geocomposites and Geojutes, Geofoam, Natural fibers – facing elements – Influence of environmental factors on the performance of Geosynthetic materials – Physical – Mechanical – Hydraulic and Endurance properties testing.
UNIT III DESIGN FOR SOIL REINFORCEMENT AND SEPARATION
Reinforcing the soil – Geotextiles and Geogrids –Retaining wall – embankment – unpaved roads – paved roads – railway tracks – Shallow foundations – seismic aspects.
UNIT IV DESIGN FOR FILTRATION, DRAINAGE AND CONTAINMENT
Geotextile filter – Filtration Mechanism – Factors affecting filter behaviour – Filtration design – Drains – Drainage in embankments – erosion control silt fences – Containment ponds – Reservoirs and Canals – Hydraulic tunnels – River bed and bank protection.
UNIT V DESIGN OF REINFORCED SLOPES
Type and orientation of Geosynthetics – Function of reinforcement against slope failure – Stability analysis – Design aspects – Embankments – Basal reinforcement – seismic aspects – General construction aspects.
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Explain various principles and mechanism of soil reinforcement.
CO2 Select different reinforcing materials based on functions to determine their properties
CO3 Design geosynthetics as a reinforcement and/or a separator for different reinforced structures.
CO4 Design geosynthetics as a filter, drainer and as a containment for
CO5 different reinforced structures. Analyze and design reinforced slopes for static and seismic loading.
