MRes - Geomechanics

Heriot-Watt University

Research developed by the Geomechanics team covers a wide range of areas, including laboratory testing, microstructure analysis, constitutive modelling and geotechnical and geoenvironmental engineering studies. In particular, researchers have an interest in unsaturated soils behaviour at micro and macro-scale. Recently, work has concentrated on testing soils at different suction and temperature levels and correlating the macro and micro-scale response. This work has special relevance to heavily compacted clays surrounding radioactive nuclear waste disposal as well as applications such as burial of high voltage cables, drilling of deep offshore wells and foundations subjected to temperature and suction changes. Research into unsaturated soils represents a relatively new area in geotechnical engineering. Climatic changes makes this topic highly relevant and research work focuses on the thermo-hydro-mechanical behaviour of these soil-water-air systems. The team collaborates with international leading researchers in this area. Work into the effects of cyclic wetting and drying on soil behaviour has been in progress for several years and is continuing. This is very relevant when investigating the effect of flooding events on soil response and microstructure.
