dc.description.abstractenglish	The accelerated growth of the industrial zone of Durán, on the Ecuadorian coast close to Guayaquil, requires the construction of structures founded on settlement-powerful strata of soft soils. The high compressibility and low shear strength of these soils create challenges in the stability of the foundations of these structures. The presence of these soils represents a complex geotechnical situation to solve, mainly due to the settlements caused by the magnitude of the overloads from different engineering projects. For the engineering design of the foundation system of any structure, the geotechnical characterization of the subsoil is required to provide reliable resistance and deformability parameters. This article presents the results and interpretation of the in-situ test campaign, complemented with laboratory data, at the Durán Logistics Terminal characterized by these soft deposits. Boreholes with standard penetration tests (SPT), piezocone (CPTU) and seismic dilatometer (SDMT) tests were carried out in different areas, both before and after the application of different preloads useful to induce a part of the settlement before the construction of warehouses. Soil samples allowed to supply soil classification and stiffness characterization, enabling accurate interpretation and correlation with in situ data. The results obtained after the removal of the preloads detect a considerable improvement of the geotechnical parameters due to the induced settlements, providing a helpful case study for the optimal the design of foundation systems in soft deposits.
