Determination of Unloading—Reloading Modulus and Exponent Parameters (m) for Hardening Soil Model of Soft Soil in Ho Chi Minh City
This study analyzes and determines the modulus of deformation and the dependence of the modulus of deformation on the stress state of Ho Chi Minh City’s soft soil: exponent parameter (m). Parameters were determined as stiffness parameters: E50 and Eur in Hardening Soil model. Also, in calculating geotechnical problems by finite element method with Hardening Soil model, engineers often use the ratio of \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$E_{ur}^{ref} /E_{50}^{ref} = 3$$\end{document} for all types of soil. However, the actual ratio is very different for each soil type. The authors proposed this coefficient as triaxial compression testing was performed for very soft clay at depths of 4–6 and 12–14 m, soft clay in the range of 18–20 and 24–26 m according to drainage conditions with unloading and reloading.
