Behavior of pile groups under lateral loads in sand soil considering mohr-coulomb and modified mohr-coulomb criterions : comparative analysis

Abstract EN

The behavior of pile groups under lateral loads depends on the soil-structure interaction which is governed by the soil properties and behavior.

In the three-dimensional finite element analysis, the prediction of the realistic soil behavior is a complex step in order to capture the realistic pile-soil interaction.

In the analysis programs, the soil behavior can be defined using constitutive models like the Mohr-Coulomb constitutive model which is widely used in representing the soil layers in the analysis, but a new modified constitutive model called the Modified Mohr-Coulomb model also used in the analysis along with other constitutive models.

The goal of this research is to compare the two constitutive models' capacity to capture the behavior of a full-scale pile group case study and validate the results to field measurements.

A good agreement is found between the measured and the computed behavior of pile groups under lateral loads using the Modified Mohr-Coulomb constitutive model.
