Geotechnical engineering is a civil engineering discipline
concerned with the engineering behavior of earth materials.
Geotechnical engineering includes the investigation of existing
subsurface conditions and materials and the determinination
of their physical/mechanical and chemical properties that are
relevant to the project considered.
The above geotechnical data are then assessed for risks posed
by site condition and used in designing earthworks, structure
foundations. A proper geotechnical investigation will also aid
in properly indentifying critical points to monitor during earthwork
and foundation construction.
A geotechnical engineering project begins with the review of
project needs to define the required material properties and the
site tests. A site investigation of soil, rock, fault distribution
and bedrock properties on and below an area of interest to determine
their engineering properties including how they will interact
with, on or in a proposed construction will follow. Geotechnical
site investigations are almost always needed in major projects
and help gain an understanding of the project area. Soil and rock
samples are typically collected with a dril rig and appropriate
samplers. The soil samples are then transported to a geotechnical
laboratory where a number of geotechnical tests are carried out.
In situ tests typically include the Standard Penetration Test
and the Cone Penetrometer Test.
Investigations typically include the assessment of the risk to
humans, property and the environment from natural hazards such
as earthquakes, landslides, sinkholes, soil liquefaction, debris
flows and rock falls.
Based on the test and in-site (in-situ) tests an engineer can
design all required foundations, earthworks, pavement subgrades,
etc. Such foundations may be constructed for various size structures
such as deep basements, high-rise buildings, bridges, medium to
large commercial buildings.
Foundations built for above-ground structures include shallow
and deep foundations. Retaining structures include earth-filled
dams and retaining walls. Earthworks include embankments, tunnels,
dikes, levees, channels, reservoirs, deposition of hazardous waste
and sanitary landfills.
Geotechnical engineering is also critical in the successful design
and construction of wharves, marinas, and jetties. Ocean engineering
can involve foundation and anchor systems for offshore structures
such as oil platforms.
