Abstract: Volume and pore water pressure variations that develop in saturated soils due to temperature changes are expressed in terms of the thermal expansion of the soil components, compressibility of the soil and physico-chemical effects. While the compression index of remolded illite was found independent of temperate, the higher the temperature the lower the void ratio at any given consolidation pressure. The magnitude of pore pressure change accompanying temperature change under undrained conditions is controlled primarily by the compressibility of the soil and thermal expansion of pore water. Results are useful for assessing the effects of temperature variations on properties of soils, the assessment of necessary laboratory temperature control during undrained tests, and the study of physico-chemical phenomena in soils.
