Nonlinear analysis of the influence of increments amounts and history load on soil response

Krešo Ivandi and Božo Soldo

Abstract

The soil response calculation is described, by which, threw the fictive path of stress, the stress-deformation diagrams are determined, considering the nonlinear soil behavior. The calculation are lead incrementally, by which is shown that in the presented soil model (modified Cam Clay), considering the influence of overconsolidated soil pressure OCR, the number of calculation steps may, but not necessarily, have a sufficient influence on the value of failure load and definite soil deformation. The simplicity and the practicalness of the procedure, the enables modeling the complex relations in soil.

Key Words

nonlinearity; average normal stress; deviation stress; plasticity; increment; calculation; volume and deviation deformation; modified Cam clay model.
