Plaxis 2d handbook3/11/2024 ![]() ![]() It is also seen that the crack pattern of the cement-soil column is more realistic for the CM than MCM due to the consideration of the softening behaviour. The results have shown a good agreement between the simulation of the CM and the test result. 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. ![]()
