Course Description

The student is expected to learn:soil consolidation and stress distribution in soil media, shear strength of soil, lateral earth pressure-active and passive conditions, bearing capacity of shallow and deep foundations, stability of slope and soil dynamics.


Grading Policy:Final exam(70%), Midterm exam and assigned homework(30%)

Course Goals

The course objective is to provide an understanding of key engineering properties and mechanical behavior of soil materials including consolidation, shear deformation and strength properties, bearing capacity of foundations, stability of slopes and excavations, and dynamic properties of soil.
At the end of the course, students will be able to:
1.Understand the principles of strength and deformation behavior of different soils.
2.Understand and apply the fundamentals of soil mechanics and geotechnical compitation methods.
3.Understand the soil-structutes interaction.

Course Topics

Consolidaton 2 Understand Terzaghi's theory of consolidation, laboratory consolidation test, field consolidation curve, normally consolidated condition and over consolidated condition, and problems on final and time rate of consolidation.
Stresses in ground 1 Understand stresses in the ground due to loading, soil strength and pressure distribution below foundation.
Shear derormation and shear strentgh 2 Understand measurement of shear strength and triaxial compression tests, strength parameters, drained and undrained behavior of clay and sand, and stress path for conventional triaxial test.
Theories of earth pressure 2 Understand the lateral earth pressure in active and passive states, Rankine's theory in cohesive and cohesionless soil, Coloumb's wedge theory with condition for critical failure plane, earth pressure on retaining walls of simple configurations.
Midterm exam 0.5
Bearing capasity of foundation 1.5 Understand the definition of bearing capacity, ultimate bearing capacity, net ultimate bearing capacity, net safe bearing capacity and allowable bearing pressure, and derivation of Terzaghi's general bearing capacity equation for continuous footing and basic numerical problems associated with it.
Slope stability 2 Understand the failure mechanisms of both infinite and finite slopes and methods of slope stability analysis.
Soil dynamics 2 Understand the nature of dynamic loads, mchanism of liquefaction and liquefaction parameters, and stress conditions on soil element under earthquake loading.
Infrastructure and ground 1 Understand the recent geoengineering projects and ethical responsibility for geoengineers.
Feedback 1 Understand the intentions and correct answers of the questions given in the examination.
