Geotechnical study in Province of Zaragoza

Zaragoza province, located in the north-eastern region of Aragón, has a diverse geographical and territorial landscape that influences the ground characteristics for geotechnical studies. The surface is distributed between the Ebro depression, where alluvial and silty soils predominate, and the mountainous areas of the Pyrenees and the Iberian System, with rocky and scree soils. The comarca of las Cinco Villas and the Hoya de Huesca area exhibit clayey soils with good drainage capacity, ideal for stability analyses. The areas closest to the capital, in the Ebro depression, feature recent alluvial sediments, with variable cohesion and compaction, which require specific assessment when designing foundations.

Likewise, the geographical orientation and climatic conditions of Zaragoza, with cold winters and hot summers, affect the compaction and moisture content of the soils; these are crucial aspects for planning the structure and the stability of buildings. In areas such as the Valle del Jalón or the left bank of the River Ebro, the variability of the soil type influenced the technical recommendations for the selection of foundations, prioritising a prior geotechnical analysis.
