Simulation of triaxial CD test from 'Koševo layers' applying Soft Soil model in software program PLAXIS

Abstract

For the purposes of defining the parameters of the model behavior 'Koševo layers' geomechanical laboratory tests were performed such as classification test and deformability test in oedometar test and shear strength test in consolidated undrained conditions (CU test) and in consolidated drained conditions (CD test). Simulation of triaxial test in software package Plaxis was performed with several models. Model simulations with application of different models of soil behavior is trying to find out which model best supports the model behavior of the tested soil material. The paper presents the results of simulation of triaxial CD test with Soft Soil model in software package Plaxis, based on finite element method and a comparison with laboratory results.
