In order to understand the trigger mechanism of slow‐moving landslides occurring in the early cold season from late autumn to winter, we investigated the effect of temperature on the shear strength of slip surface soils. Displacement‐controlled and shear stress‐controlled box shear experiments were performed on undisturbed slip zone soils under residual strength conditions. Test results conducted at temperatures from 9 to 25°C showed remarkable shear strength reductions with decreasing temperature. Creep‐like slow shear displacements were induced by a decrease in temperature. These temperature‐dependent shear behaviors are attributed to the rheological properties of hydrous smectite that dominantly compose the soil material along the failure surface. Our experimental results imply that ground temperature conditions influence slope instability, especially for shallow landslides occurring in smectite‐bearing rock areas.

“…After the discussion on experimental phenomena, a thermoplasticity stress-strain relationship was established and the mathematical formulation of thermoplastic yield function was introduced too. The work of Abuel-Naga et al included some isotropic and anisotropic consolidation tests as well as drained and undrained triaxial tests of several different saturated clays [17,18], and then a thermomechanical model was built based on the modified Cam-clay model [19]. Through application of a temperature-controlled triaxial apparatus, triaxial tests through three different stress paths under different temperatures were carried out by Chen et al [20] to demonstrate that the transformation and strength characteristics of clays were affected a lot by temperature change.…”

The influences of temperature on the mechanical behavior of saturated clays are discussed first. Based on the concept of true strength and the revised calculation method of the potential failure stress ratio, the equation of the critical state stress ratio for saturated clays under different temperatures is deduced. Temperature is introduced as a variable into the UH model (3-dimensional elastoplastic model for overconsolidated clays adopting unified hardening parameter) proposed by Yao et al. and then the UH model considering temperature effects is proposed. By means of the transformed stress method proposed by Yao et al., the proposed model can be applied conveniently to 3-dimensional stress states. The strain-hardening, softening and dilatancy behavior of overconsolidated clays at a given temperature can be described using the proposed model, and the volume change behavior caused by heating can also be predicted. Compared with the modified Cam-clay model, the proposed model requires only one additional parameter to consider the behavior of the decrease of preconsolidation pressure with an increase of temperature. At room temperature, the proposed model can be changed into the original UH model and the modified Cam-clay model for overconsolidated clays and normally consolidated clays, respectively. The considered temperature range here is from the melting point to the boiling point of the pore water (e.g. the experimental temperatures (20°C-95°C) mentioned in this paper are within this range). Comparison with existing test results shows that the model can reasonably describe the basic mechanical behavior of overconsolidated clays under various temperature paths. clays, constitutive model, overconsolidation, temperature Citation:Yao Y P, Yang Y F, Niu L.
