What geotechnical engineering?
-
It is the story of engineering relationship between humans and earth
It is the science that explains the mechanics of soils and rock, and its engineering
application’s development to human kind.
In early times the practice of Geotechnical engineering was applied by trial and error,
observational experience and empirical experimentation, problems such as the notorious
leaning tower of pisa. Prompted Engineers to begin taking a more basic scientific
approach to geotechnical engineering
1700 – 1900
Coulomb, Darcy, Rankine, Boussiness, Mohr, Atterberg
Published fundamental theories on soil mechanics and water flow through soil
Several organization and society were formed to the early 1900 to advance its field of civil
engineering, particular recognition is given to Karl Terzaghi who is considered to be the father
of modern geotechniques with his classic book on soil mechanics published in 1925
What is the international society for soil mechanics and geotechnical engineering?
In 1936 along with fellow colleagues from 20 different countries. Tataki founded soil mechanics
and geotechnical engineering. He became its first president. Today, the International Society has
more than 89 countries. Members involving over 19,000 individuals in the geotechnical
engineering profession. Most of what the technical engineers do is hidden below the ground
surface yet it is a very important discipline with a vast Scope as all construction has the rest on
or in the ground. Soil is a complex material which? Which is very valuable in grain size,
cementation, strength, and behavior. This renders the task of a geotechnical engineer among the
most challenging tasks in civil engineering. Geotechnical engineers use fundamental principles
of soil and rock mechanics to investigate subsurface conditions. This allows them to evaluate and
design activities such as. The stability of natural slopes and man-made soil deposits, so with cuts
and fills, shallow and deep foundations, dams, retaining walls, and many other works. Directly
interacting with the subsoil and water.
In order to meet the diversity of challenges the profession faces. the International Society
has created 30 technical committees over the last 50 years, each representing. A particular
aspect of geotechnical engineering. Foundation engineering is one important area of
geotechnical engineering. The foundation of every structure should be designed to withstand
man-made and natural loads. Vertical and lateral pressures are created by earthquakes and
high winds as well as the weight of the structure itself. Buildings, skyscrapers, bridges, and
other superstructures have to bear on shallow footings mats or pile foundations. Shoring
systems include bracing of deep excavations, nailing of landslides, and the support of tunnels
to name a few. Any geotechnical engineering project is different indeed the soil at a site is
likely different from any other site. As a result, the most common first step of any geotechnical
project is the site investigation, it starts by drilling into the soil and rock testing them in the
field or collecting samples which can then be analyzed in a laboratory. Once soil and rock
properties are determined the geotechnical engineer can design the project including its
environmental impact, investigations can 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 rockfalls.
Geotechnical engineering can significantly influence the sustainability of infrastructure
development because of its early position in the construction process given the intensive
research carried out in the impressive geotechnical advancements are made on a regular
basis. Most of these innovations are often hidden from the public eye since the work is
underground. These innovations are however a crucial part of a success story, they can be
temporary in nature such as deep excavation and support to construct a high-rise tower like
Borg Halifa or permanently embedded such as the complex foundation system of the Rianna
and Tyrion bridge. The build environment where we live serves as the dynamic interface
through which humans and the ecosystem interact and influence each other. Understanding
this interdependence is key to fathoming the impact of geotechnical engineering on society.
Throughout history, geotechnical engineering has made changes in the way we live or even
think. Projects like building the Aswan dam, laying the foundation of Golden Gate Bridge,
digging the Panama Canal, stabilizing the cliffs at Point New York or giving new life to the
Tower of Pisa have affected past and present generations such projects large and small will
continue to impact and shape our future. It has been a cycle of sharing knowledge and gaining
knowledge of accomplishments and lessons learned the International Society for soil
mechanics and geotechnical is proud to be at the center of this field emblematic of human
achievements.
