Course Aim: To impart knowledge on ground improvement techniques and appropriate use of geosynthetics.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢      select the most suitable ground improvement technique for a given situation.

➢      describe different types of geosynthetic materials and recommend appropriate laboratory tests to determine their engineering properties.

➢      design a drainage and/or filtration system for engineering applications using appropriate geosynthetic materials.

➢      design an appropriate ground improvement technique for a given situation.

Course Content:

➢      Introduction to ground improvement techniques

➢      Geosynthetics: Introduction, materials, testing, applications, design for filtration and drainage

➢      Design of Preloading and vertical drains, vacuum consolidation, stone columns, dynamic compaction

➢      Soil stabilization: Lime, cement, fly ash etc.
