Indian geotechnical journalSummary: Temperature changes in saturated soils may result in volume change and consequently the stress–strain behavior of soils may undergo alterations. These alterations may impose implications on geotechnical stability of soils. Temperature-dependent behavior of soils has been studied in the literature, both experimentally and theoretically. Based on the experimental studies from the literature, this paper aims to review the thermo-mechanical behavior of saturated soils. First part of paper attempts to provide a conceptual insight on the thermally induced volume change behavior of saturated soil and second part reviews the experimental investigations from the literature, for a temperature range of 5–100 °C for clay and 5–600 °C for sand. These experimental studies confirm the irreversible contraction of NC clay at OCR = 1 and quasi-irreversible volume change of normally consolidated and overconsolidated clay with a low overconsolidation ratio (< 2), during drained heating. Similar behavior is also observed for loose to medium dense sand. The parameters like pre-consolidation pressure, secondary consolidation, permeability, drained and undrained shear strength also show temperature dependence.
