Whenever
any of the company wants to ensure the optimum quality of the construction as
well as longevity of the whole structure the soil has to undergo several kinds
of multiple tests so that quality can be verified very easily. Depending on the
nature and behaviour of the soil several kinds of load conditions will always
vary. So, one of the best qualities which the companies must test in the soil
is the strength. For this purpose, the companies must contact the triaxial
testing instruments manufacturer so that they can have
proper access to several kinds of equipment which will further help in
conducting the tests efficiently and effectively.
The
tri-axial test can be termed as the geotechnical test that is used to test the
mechanical properties of the soil. In this particular testing system, the
sample of the soil is put under the pressure till the point of shear is
achieved. This particular test can be conducted on distributed high-quality
soil so that several kinds of qualities for example sheer strength, cohesion
and stress can be measured very well. The size of the samples which have been
used for testing will also vary from 8mm-100
mm. Companies can also go with the option of conducting the testing on larger
sample size as well.
This
particular concept will always help in preventing the drainage of the specimen
and will also measure the pore pressure, permeability and the stiffness about
soil as well as other things. Hence, this particular testing can be very
effectively utilized to solve all the problems at the time of constructing the
dams, tunnel linings and analysis of several other things so that total stress
measure can be dealt very well.
Following
are the types of tests which are used in this particular test:
-Unconsolidated
undrained test: Under this particular test the sample soil is
subjected to cell pressure so that there are no issues. The cell pressure can
also be applied so that soil increases in terms of pressure.
-Consolidated
undrained test: Under this particular test there are some
of the variations and the drainage is sometimes permitted during the
application. The process will also become constant without any kind of
permission.
-Consolidated
drained test: This particular test is known as the slow
test and in this particular set up the stress is also applied on the soil which
is drained. Soil-pressure will always remain constant and excess pressure will
be avoided by slowly applying the loading. These kinds of the specimen are
tested in the membrane and the little pressure is applied until the point of
failure. The basic motive of conducting these kinds of tests is to have proper
and accurate readings of the angles of internal friction as well as cohesion in
the soil samples.
Nowadays
companies also go with the option of utilizing several kinds of software along
with equipment to conduct these kinds of tests. Hence, triaxial analysis equipment is very well used to conduct these
kinds of tests so that the quality of the soil can be assessed and usability
can be determined.
