Course Learning Objectives
The objective of this course is:
- To enable the student to appreciate how Meyerhof’s general bearing capacity equations are important
- To teach the student special methods of computation of settlements and the corrections to be applied to settlements.
- To enable the student to understand the advanced concepts of design of pile foundations.
- To teach the student the problems posed by expansive soils and the foundation practices appropriate to expansive soils.
- To enable the student to learn the difference between isolated and combined footings, the determination of bearing capacity of mats and proportioning of footings.
Course Outcomes
Upon successful completion of this course, student will be able to
- Compute the safe bearing capacity of footings subjected to vertical and inclined loads.
- Understand the advanced methods of settlement computations and proportion foundation footings.
- Appreciate the methods of computing the pull-out capacity and negative skin friction of piles and compute the settlements of pile groups in clays.
- Appreciate the problems posed by expansive soils and the different foundation practices devised.
- Appreciate the difference between isolated footings and combined footings and mat foundations.
