Course Description

Students are expected to learn consolidation and stress distribution in soils, shear strength of soils, lateral earth pressures, bearing capacity of shallow and deep foundations, slope stability, and soil dynamics. Fundamental analyses and design criteria of various geotechnical engineering problems are drilled through exercises.


Final Exam (70%), Midterm exams and homework (30%)

Course Goals

The course objective is to provide understanding of key engineering concepts and mechanical behaviors of soil materials including consolidation and soil improvement, load transmission in elastic medium, effect of excessive pore water pressure to shear strength, effective stress paths interpreted from conventional triaxial tests, lateral earth pressure acting on retaining walls, bearing capacity of foundations, stability of slopes and excavations, soil liquefaction, and dynamic characteristics of soils subjected to earthquake.

Course Topics

Theme Class number of times Description
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 strength 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.
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 capacity 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 and liquefaction 2 Understand the nature of dynamic loads, mchanism of liquefaction and liquefaction parameters, and stress conditions on soil element under earthquake loading.
