Triaxial shearing tests at various temperatures and various effective confining pressures were performed on Boom Clay samples under undrained conditions. Test results clearly show that under the same hydro-mechanical conditions, an increase in temperature can cause a decrease of shear strength of Boom Clay. This weakening in shear strength was further interpreted as the reduction in cohesion and elastic modulus, and also the pore pressure build-up due to temperature elevation.

The results obtained confirm the effect of the overconsolidation ratio (OCR) on the thermal volume changes (contraction or dilation).
