The comparison of the model using the CM and Mohr-Coulomb model (MCM) were also conducted. The model was calibrated based on the results of the unconfined compression tests of the treated soil, then used for the analysis of an excavation using the cement-soil column as the retaining wall. The Concrete model (CM), which can capture hardening and softening behaviours for both compression and tension, was used to simulate the cement-treated soil in this study. However, the treated soil becomes brittle and the strength reduces significantly in post-peak stress. The cement-treated soil is one of the soft soil treatment methods, improving engineering properties of soft soils. ![]()
