Subject Title
Soil Mechanics and Foundations

Subject Description
This subject introduces the students to the geotechnical properties of soil required for an elementary engineering evaluation of a shallow foundation and earth stabilization structure.  Laboratory tests required for determination of soil's shear strength will be introduced and practiced.  Subsurface stresses, seepage stresses, capillary water and its effects as well as stress distributions of applied loads are covered.  Bearing capacity and settlement calculations will be evaluated for various foundation systems and soil conditions.  Lateral earth pressure will be calculated for both cohesive and cohesionless soils and the corresponding stability of earth retaining structures.

Credit Status
One subject credit in the Civil Engineering Technology program.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

  1. Utilize Mohr’s circle of stresses to evaluate shear strength within a soil mass.
  2. Calculate Total, Neutral and Effective stresses in soils and draw stress profiles for in-situ soils.
  3. Calculate stress distribution beneath shallow foundations using both Boussinesq and Westergaard analyses.
  4. Conduct shear strength tests to determine cohesion and the angle of internal friction for cohesive, cohesionless and mixed soil types.
  5. Calculate settlement due to imposed footing loads for normally and overconsolidated clay soils.
  6. Evaluate bearing capacity from empirical methods based on the Standard Penetration Test and the General Bearing Capacity formula based on shear strength.
  7. Calculated lateral earth pressure and stability for gravity and cantilever retaining walls using the Rankine analysis for both granular and cohesive soils.
  8. Calculate the stability of cut slopes for unsupported excavations and embankments.

Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.

All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment. Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated.
