Abstract

Determination of creep parameters used in constitutive modelling of cohesive soils.A b s t r a c t. The paper presents methods of determining creep parameters based on uniaxial compression testing. Relevant analyses were carried out on the basis of the time resistance concept. Evaluation of the strain-time one-dimensional behaviour of soil is also described. The aim of this research was to put some light on methods of determination of creep parameters used in various constitutive creep models and to develop the reliable interpretation approach. In this work the values for creep parameters were defined with the help of oedometer tests on reconstituted clay samples from Chmielów.
