Geotechnical Engineering is:
That branch of civil engineering that
deals with soil, rock, and under-ground wateri.e. the use of soil and
rock as a construction material.

Issues addressed bygeotechnical engineers: Can the soils support the structure?
What will the groundwater due in the future and
how will that affect the structure?
What is the impact of grading, excavation or
filling?
Are the earth and rock slopes stable?
What type of foundations are best suited for the
structure?

What type of retaining walls if used are
required?
How will the site respond to an
earthquake?
Is the site contaminated?
How can a contaminated site be
remediated?

To complete a geotechnical
engineering project one must: Understand the nature of the structural and
geotechnical loading
Understand the geological setting of the
construction site
Understand the engineering behavior of thesoils that will carry the structural loads
Understand the interaction between the soil
and rock and the foundation elements.

For every project thegeotechnical engineer must:
Study the geology of the site and how it
affects the planned construction
Investigate the surface and subsurface
geotechnical materials
Conduct field and laboratory tests to
ascertain the necessary engineering
properties of the soil

Determine the most economical foundation
system compatible with the geotechnical
properties of the site and the needs of the
structure.
Develop appropriate construction
procedures.
Monitor the progress of construction

CE 353 Soil Mechanics will:
Focus on understanding the engineeringbehavior of soils:
Strength
Deformation
This requires an understanding of:

The effect of particle grouping (packing) onthe engineering properties of soil.
The very important effect of water on theengineering properties of soil.
An understanding of how stresses aretransmitted to and through soil material
The effect of the transmitted stresses on thedeformation of soil elements, and
An understanding of how soil fails under load.
