Consistency limits are simple and precious soil parameters that
are directly representing the mineralogical and physical properties and
indirectly used to estimate the strength and rigidity characteristics of fine
grained soils. The consistency tests are assumed as the easiest and the basic
tests of geotechnical engineering and the application details of the tests are
depending on the experience of the operator and the environment conditions.
Therefore, the reliability and correctness of the tests are still in the
concern of geotechnical studies. Besides, the development of information and
computer technologies also present alternative solution perspectives for the
attainment of geotechnical properties. In this connection, the regression
analysis and artificial neural network applications become the most preferred
techniques to estimate the consistency limits with the use of an only a variable.
In this study, it is aimed to obtain the
consistency properties of high plastic clays that are procured from the site
investigation reports conducted for Bakırköy district (Istanbul, Turkey)
depending on only the evaluation of liquid limit test results. A database is
arranged with the use of approximately 450 consistency limit tests. Linear and
multi-linear regression analyses and artificial neural network applications
were conducted with the use of different variants such as depth and fine content
to determine the plastic limit and the plasticity index value. As a result,
comparisons of the applied techniques are done to query the appropriateness of
the methods and to find the approximation rate to the actual value. Consequently,
the success of the applied techniques was tried to be shown with the developed
equation set.
