Soil response to loading depends on subsoil history and boundary conditions of the analysed problem. Hence the conclusion that parameters of soil constitutive models are also dependent on these factors, especially when simple models are considered. The paper presents a new approach to parameters evaluation, called Loading Path Method, based on Stress Path Method by Lambe and Strain Path Method by Baligh. The problems connected with the new method are discussed.
