Cohesive soils give rise to difficulties concerning the stability of slopes and no effective preventive measure has yet been found. In the recent years the thermal treatment of soils for improving the stability of cohesive soil was attempted in U.S.S.R.. The procedure of thermal treatment aims to strengthen the soil around the boring hole by burning the oil for long time. The aim of our experiment is due to determine the transient temperature and moisture distribution around a hollow cylinder in which the temperature is kept constant and to estimate the effective range of strengthening of soil by thermal treatment. Using the thermal diffusivity, rate of drying and moisture diffusivity at a given temperature, the moisture and temperature distribution corresponding to a given time can be calculated. Concerning the field procedure, several examples are explained.
