Estudio geotécnico in Cabañas Raras

In Cabañas Raras, soils formed by sandstones, conglomerates and flysch predominate, accounting for 76,35% of the territory. This type of substrate generally offers good bearing capacity and favours direct foundation solutions, especially in layers that are neither altered nor fractured. Compact gravels and sands, although less frequent, also contribute positively to the stability of structural supports. Conversely, the occasional presence of fine sands and silts may require additional checks to rule out problems of differential settlement, although their influence is considered secondary in the area.

From the seismic point of view, Cabañas Raras shows high activity, with more than 150 events over 30 years and a maximum magnitude (Mmax) of 4,7, which implies that seismicity must be integrated into the calculation and design of structures. The expansiveness associated with the occasional presence of expansive clays is subordinate or limited to areas with low climatic incidence, such that the risk of expansiveness is not significant at most sites within the municipality. The main limiting factor of the geotechnical studies in the area lies in the high seismicity, making it necessary to adopt a specialised approach to structural safety under dynamic loads.
