AB - A new temperature-controlled oedometer has been designed at Imperial College London and commissioned to investigate the thermo-hydro-mechanicalbehaviour of soils. Temperature control is achieved by submerging the specimenin a water bath. The water temperature is regulated byheaters positionedradially around the specimen, or by an external unit. The temperature can be varied between 5°C and 85°C. The temperature gradient across the specimenis minimised by circulating water beneath the specimenthrough a hollow plate.A thermo-mechanical, elastic, finite element model of the equipment has been produced using the Imperial College Finite Element Program (ICFEP). The experimental results are used to develop and validate the numerical model. The model is then used to inform and improve the experimental testing programme.The accuracy of temperature control has already been established. The testing programme includes heating tests at constant applied stress, and loading tests at discrete temperature values. Of particular interest is thermally-inducedoverconsolidation behaviour. The experimental results are used to verify the existing numerical framework and to establish the effect of temperature on the behaviourofsaturated soil.
