 ABSTRACT

soils in relation to other geotechnical parameters whose determination is easily given. These models were then applied to our database which consists of 35 free swelling tests performed on reconstituted samples. This application has shown that it is difficult to generalize these models to any type of soil. We also proposed specific models in our tests taking into account the increasing of the factors number. The results have show that the pressure correlates better than the amplitude and the inclusion of a higher numberís parameters in the model improving the later performance.

Keywords: Clays, swelling, statistical models, estimates, measurements.
