摘要: Abstract In this paper, a critical state based thermo-elasto-plastic constitutive model is developed for destructured, naturally structured and artificially saturated clays. The an extension of the previously thermo-mechanical by authors clays, considering effects structure on mechanical behaviors soil. It change in position normal consolidation line (NCL) compression plane ( e − ln p ′ ) due to soil's variation temperature. present able simulate behavior clays triaxial at elevated temperatures lower than boiling point water. An attempt has been made use lowest possible number parameters compared with that Cam–Clay ensure these new have clear physical interpretations. sufficiency was verified test results soils using thermal tests.
