| Abstract | A series of laboratory tests on soft Bangkok clay specimen had been directed to study the influence of high temperature on its thermo-mechanical behaviour. Soil specimens were tested at different stress histories of OCR 1, 1.5, 3, 9 and different stress levels (200, 300, 400 kPa) at different temperature levels (25, 70 and 90oC). The thermally-induced volume change was determined during drained heating while the undrained shear strength and excess pore water pressure were investigated in triaxial temperature-controlled compression test. The heated specimen was sheared at high temperature at a constant consolidation pressure. The extent of heatinduced volume deformation was more significant in NC clay. NC clay specimen exhibited only contractive behaviour. However, OC clay showed initial dilation and then contraction when subjected to thermal load. The undrained shear strength increased in both NC and OC clays. The effects of temperature were irreversible with heatingcooling cycle as the shear strength remained identical compared to the specimen sheared at high temperature. |
