JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives:

• To impart Knowledge on Site investigation and soil testing methods.
• To be able to design types of foundations, suitable for different Structures.
• To identify soil types suitable for construction.

Course Outcome

At the end of the course, student will be able to

• Plan and select the soil exploration method in the field
• Estimate the bearing capacity and settlements of shallow foundations for different infrastructure projects
• Design deep foundations under different types of loads
• Design foundations for Highrise buildings, towers, chimney etc
• Design foundations on soft or problematic soils and supporting systems for excavations
