Estudio geotécnico in Bellvei

In the municipality of Bellvei, compacted gravels and sands predominate, accompanied in a considerable proportion by limestones, dolomites and marbles. This grain-size composition ensures good bearing-capacity conditions for shallow foundations, although the compaction and local homogeneity of the sandy and gravelly deposits must be assessed. The carbonate lithologies allow conventional foundations, but it is essential to correctly identify the presence of competent strata and the depth of any possible underground aquifers, which may alter the soil’s behaviour over time.

Seismicity in Bellvei is very low, with only a single event recorded over thirty years and a maximum magnitude of 3.6, which implies modest requirements for structural seismic design. The area shows no problems of karstification or expansive soils, since the subsoil is not clayey, eliminating risks associated with volumetric expansiveness. The determining factor in the local geotechnical study is the verification of the density and continuity of the granular materials, as well as the potential influence of deep aquifers on the stability and durability of the foundations.
