OBJECTIVES:

  • 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.
