The effect of temperature on the mechanical behavior of the soils around the special geo-structures, such as nuclear waste containers and energy piles can’t be neglected. In this paper, some temperature-controlled laboratory test results are selected and analyzed, based on which and the thermal induced changes of main mechanical features (e.g., shear strength, critical state line, preconsolidation pressure) are identified. A constitutive model is then developed to interpret the temperature dependent behavior of saturated clays under the framework of critical state theory. Only one temperature related parameter is added in the present model comparing with the Modified Cam Clay model, and this parameter can be directly obtained from the yield loci of the soil. The performance of the proposed model is demonstrated with simulating temperature tests under drained condition.
