Estudio geotécnico in Tudela de Duero

In Tudela de Duero, soils of compact gravel and sand predominate, providing good bearing capacity for conventional foundations, thereby facilitating the design and execution of the substructure of buildings. The significant presence of limestones, dolomites and marbles implies the existence of hard, stable bedrock in certain areas, although a relevant proportion of gypsum, anhydrite and salts is also observed, which introduces a potential risk of dissolution that must be taken into account, particularly to avoid differential settlements or damage to foundations. The extensive coverage of highly permeable aquifers makes it advisable to assess the groundwater level and possible drainage arrangements in the geotechnical study, especially in areas close to water bodies.

The seismological analysis of the area reveals high seismic activity, with 200 events over 30 years and a maximum magnitude (Mmax) of 4.7; this level of seismicity requires incorporating seismic parameters into structural design in accordance with current seismic regulations. In addition, there is karst development in the carbonate formations, so it is essential to verify the presence of cavities or dissolution processes in the subsurface before establishing any type of foundation. Since the substrate is non-clayey, the risk of expansivity is ruled out, with the main controlling factors being the influence of karst and the high seismicity in the planning and geotechnical justification of projects in Tudela de Duero.
