Abstract

– This paper presents an application of using deep cement mixing method to construct a river wall. The geotechnical characteristics, construction sequence and its behaviours were presented in this paper. The behaviours of river wall were simulated by 3dimensional finite element by using Midas GTS NX software. The different type of constitutive models of cement admixed clay were used in the analysis. The stress-strain simulation of stress path triaxial test for cement admixed clay was conducted using SoilTest feature in GTS NX software. The Mohr Coulomb model showed the best performance to predict the deformation characteristics of cement admixed Pasak Clay among UBCSand Model and Hardening Soil Model. The predicted stiffness from stress response develops overestimated the stiffness of cement mixed clay when having low mean stress. The three-dimensional finite element analysis can predict the overall behaviours of river wall improved with cement. The best model for cement admixed clay was Mohr Coulomb Model. © 2022, Avestia Publishing. All rights reserved.
