Advanced soil parameters determination for Ho Chi Minh city soft clay to predict ground movements in deep excavations and tunneling
The Hardening Soil model (HSM), an advanced soil model, is acknowledged as the suitable soil constitutive law for deep excavation analyses. In this paper, the HSM parameters of Ho Chi Minh (HCMC) soft clay were determined in a high-quality laboratory test program and are recommended for local design practice. The undisturbed clay samples were collected from two sites in the city central soft ground zone. The test program includes: (i) Oedometer tests for investigating the consolidation characteristics i.e. compression and swelling indices and oedometric moduli, and (ii) Isotropically consolidated both undrained and drained triaxial tests (CID and CIU tests) for investigating strength parameters and stress-strain characteristics including loading and unloading-reloading moduli.
