Empirical analysis of skin friction under variations of temperature

摘要

In soil geotechnical characterization, the strength parameters, cohesion (c) and internal friction angle (Φ) have been traditionally measured without taking into account temperature, which is a very important issue in energy geostructures. The present document analyzes the variation of these parameters in soil-concrete interface at different temperatures. A series of traditional direct shear tests, with a forced plane of failure, were carried out to determine the variation of skin friction with granular and cohesive soils with temperature.
