Geotechnical Engineering

 

About

The Geotechnical engineering division in the Civil engineering department was established in the early 1960’s. Since then, the division has been offering post-graduation programmes and carrying out advanced research & consultancy projects in various areas of Geotechnical Engineering. Major areas of research in the Geotechnical engineering includes physico-chemical behaviour of soils, strength and deformation behaviour of soils, soil dynamics & earthquake engineering and machine foundations, soil stabilisation, stone/sand columns, reinforced earth, geosynthetics, environmental geotechnique and waste disposal, unsaturated soil mechanics, rock mechanics, Numerical methods in geotechnical engineering.

Programs

The division offers a two year full time M.Tech Program and  research programs (MS  & Ph.D) in Geotechncial engineering specilisation. A number of theory and laboratory courses are offered by the faculty covering the diverse areas of Geotechnical Engineering. Depending on the academic necessity, the students are also encouraged to take courses in other Civil Engineering areas and other departments. Some of the  undergraduate and post-graduate courses offered in the division are:

  • Advanced Soil Mechanics
  • Soil Dynamics
  • Reinforced Soil Structures
  • Advanced Foundation Engineering
  • Elastic Analysis in Geomechanics
