ABSTRACT Temperature effects become important in a number of geotechnical applications, such as nuclear waste disposal facilities, buried high‐voltage cables, pavement, energy geostructures and geothermal energy. On the other hand, soft soils act time‐ strain rate dependent. Both temperature influence soil behavior, affecting stiffness, strength, deformation even under constant stress levels. A model to predict loading on behavior is presented this article. The based simple visco‐hypooplastic for clays encompasses key aspects coupled rate‐ temperature‐dependent (partially irreversible) thermal expansion, heating‐induced irreversible compression, history, drained heating/cooling cycles, well mechanical creep, incorporating isotachs, isotherms.
