Estudio geotécnico in Pobra de Trives, A

In the municipality of A Pobra de Trives, the dominant geotechnical subsoil is formed mainly by granite, gneiss and other igneous rocks, which constitute more than 89% of the ground; occasionally, slates and schists also appear. These materials, of a rigid nature and high strength, provide favourable bearing capacity for shallow foundations, although their low permeability may require special attention to surface drainage to prevent problems due to the build-up of water in specific areas.

The area shows high seismic activity, with 200 events over 30 years and an estimated maximum magnitude of 5, which implies that seismic actions must be considered in the structural design of buildings. Since the subsoil is not clayey, the risk of expansiveness is ruled out in this municipality. The main constraint in the geotechnical study will therefore be seismicity, which must be appropriately taken into account in the design and construction works.
