Abstract Summary
1. A new direct shear setup to measure the non-isothermal shear strength of the partially saturated soils and the soil-structure interface is developed. 2. The apparent interface friction angle is not significantly affected by matric suction at varying temperatures, but a slight decrease has been observed upon heating at all matric suctions. 3. Apparent adhesion increases with temperature increase/decrease, with a decreasing rate as suction increases, while the interface desaturation leads to higher apparent adhesion at all temperatures, corresponding to peak and residual values.
