Course Learning Objectives
The objective of this course is:
- To impart to the student knowledge of types of shallow foundations and theories required for the determination of their bearing capacity.
- To enable the student to compute immediate and consolidation settlements of shallow foundations.
- To impart the principles of important field tests such as SPT and Plate bearing test.
- To enable the student to imbibe the concepts of pile foundations and determine their load carrying capacity.
Course Outcomes
Upon the successful completion of this course:
- The student must be able to understand the various types of shallow foundations and decide on their location based on soil characteristics.
- The student must be able to compute the magnitude of foundation settlement and decide on the size of the foundation accordingly.
- The student must be able to use the field test data and arrive at the bearing capacity.
- The student must be able to apply the principles of bearing capacity of piles and design them accordingly.
