JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives:

• 1. To appraise soil and rock exploration procedures
• 2. Develop the understanding of different soil and rock parameters required for design of foundations
• 3. Learn and apply advanced soil exploration methods

Course Outcomes

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

• 1. Implement subsurface investigation based on the requirement of Civil Engineering project and site conditions.
• 2. Execute different subsurface exploration tests, collect disturbed/undisturbed samples for laboratory tests and can suggest design parameters.
• 3. Differentiate methods for estimation of dynamic soil properties
• 4. Apply instrumentation scheme for monitoring of critical sites
