Credits : 2

Prerequisites : –

Compulsory/Optional : Optional

Aim(s)
To impart knowledge on appropriate use of geosynthetics and on design of a suitable method of ground improvement.
Intended Learning Outcomes

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

  1. Describe methods of ground improvement and to select the most suitable ground improvement technique for a given situation.
  2. Recognise different types of geosynthetic materials and to evaluate their engineering properties.
  3. Design a suitable ground improvement system using appropriate geosynthetic materials where required.
  4. Evaluate the performance of soil stabilization, stone columns, jet grouting and deep mixing methods of ground improvement.
