Abstract: With the development and utilization of geothermal resources in Southwest China, temperature-induced changes in soil engineering properties have become increasingly significant. Investigating the consolidation and shear behavior of lateritic clay under varying temperatures is of strategic importance. In this study, a series of temperature-controlled triaxial consolidation and shear tests were conducted using a temperature-controlled triaxial apparatus to analyze the effects of temperature on the consolidation and shear behavior of saturated lateritic clay. The results indicate that the compression index and swelling index are essentially unaffected by temperature changes, whereas the preconsolidation pressure decreases with increasing temperature during thermal consolidation. Cooling causes lateritic clay to swell, while heating leads to contraction, though the magnitude of thermally induced volumetric strain is not positively correlated with confining pressure. Thermally induced residual pore water pressure persists after thermal consolidation and increases with higher confining pressure. During shear, the small-strain secant modulus and shear strength increase with rising temperature, which is attributed to increased cohesion. In contrast, the internal friction angle and critical state line slope show no significant changes with temperature.
