and ROUND TABLE
Geomechanics involves both the built and natural environment and their interface. It is devoted to the understanding of the mechanical behavior of geomaterials (soil, rock, concrete, bricks and other porous materials) under various environmental conditions involving the interaction with other fields such as heat and fluid flow, chemical reactions and others. The theories and models developed in this context find applications in a many fields of engineering: earth dams, embankments, and natural sites such as slopes and cliffs; conventional and non-conventional energy production, reservoir engineering and mining, and their influence on the geosphere; the built environment, architectural heritage, underground structures such as tunnels; waste disposal, pollution, depollution and environmental protection through good practice; natural hazards such as seismic actions, debris flow and avalanches and others.
Complexity is an important feature of this interdisciplinary field, and consequently experimental evidence is difficult to obtain, and laboratory as well as in situ testing procedures present serious challenges. Advanced numerical techniques are required to obtain reliable predictions and can help to develop good practices for sustainable development in this field. All this will be addressed in the symposium, by presenting problems related to a broad range of geo-environmental engineering practices.
