Sheet pile wall analysis by the computer program Plaxis using different constitutive models for soil

The paper describes the basic difference between three types of soil models, Mohr-Coulomb model (MC), Hardening soil model (HS) and newly developed hardening soil model with small-strain stiffness (HSs). The way that those constitutive models are describing stress-strain relations, is presented with basic equations and compared graphically. As more the model considers complex mechanical behavior of the soil, the more parameters are used. To evaluate the influence of each stiffness parameter on the soil behavior, several parameter analyses were performed for standard triaxial compression tests and sheet pile wall displacement problems. The results of calculated wall displacement were compared to real inclinometer measurements.
