Course Description: This course covers the basics of the discipline of geotechnical engineering with contribution to engineering science and engineering design.  This deals with the following topics: Soil mineralogy, Volume relationships, Soil classification, Water in soil, Effective stress, Compressibility, and Shear strength.

 Prerequisite: Strength of  Materials

 Teaching Assistant: 

 Textbooks: Principles of Geotechnical Engineering, by Braja Das.

Reference: Soil Mechanics, by R. F. Craig,, An Introduction to Geotechnical Engineering, by Holtz and Kovacs, Laboratory Manual for Soil Mechanics, by M. Awad.


Course Aims:


 A basic understanding of the physical and mechanical characteristic and how these relate to engineering behavior of soils {effective stress, and stress-strain soil behavior} .

 An  understanding to the steady-state flow of water through soils..

 The ability to determine the geotechnical parameters for engineering design.

 Course Intended Learning Outcomes (ILOs):

       Knowledge of geotechnical engineering.

·      Knowledge of soil properties and classifications.

·      Understanding of water seepage and flow nets.

 ·      Differentiation between effective and total stresses.

 ·      Dealing and using soil laboratory tests in order to find the soil properties.

.     Apply Soil Mechanics  concepts to stability and settlement analysis.

 ·      Development of research skills and presentation skills.

 Grading: Grades will be determined as Follows:

 Homework and Quizzes             15%  Project  Presentation              20%

 Midterm                                           25%  Final                                         40%

 There will be homework assignments for each items of the course outline consisting of textbook problems. Every student is responsible for upholding the academic integrity policy.

 Exam Dates:   Exam.   May 27, ( 12.00- 3.00)
