Estudio geotécnico in Los Yébenes

In Los Yébenes, the predominant ground is formed by sandstones, conglomerates and flysch, accompanied in smaller proportions by limestones, dolomites and marbles. These lithological materials provide adequate bearing capacity for foundations, generally being firm and consistent, with occasional zones of compact gravels and sands that can locally enhance the ground’s strength. The presence of slates and schists is also occasional, but it does not substantially affect stability given their low frequency. The dominant impermeability of these strata limits the risk of liquefaction and upward water migration, although isolated shallow aquifers may exist that it is advisable to identify during the geotechnical investigation.

The surroundings of Los Yébenes are characterised by high seismic activity, with more than 150 events over 30 years and a maximum recorded magnitude of 5.1, an aspect that must be rigorously considered in structural design, particularly when choosing the type and depth of the foundation. The ground is not clayey, which eliminates the risk of expansivity, and the absence of karstic phenomena simplifies the preliminary analysis. Seismicity is the main geotechnical constraint for any project in the area, requiring a detailed study of local seismic response.
