dc.description.abstractenglish	Rammed Aggregate Piers® (RAP) and Stone Columns by vibro replacement (SC) are among the methods used for the construction of vertical gravel elements, increasingly employed as ground soil improvement techniques. This study describes and analyzes the performance of 41 RAP elements and 12 SC elements (53 in total) installed in two wastewater treatment plants (WWTP), located in the north and south of the city of Guayaquil (Ecuador), specifically along the banks of the Daule and Guayas rivers, respectively. The analysis includes geotechnical characterization generated through the interpretation of in-situ and laboratory tests, along with load tests and settlement plates, to provide design recommendations for ground improvement of alluvial and deltaic estuarine deposits, consisting of high plasticity, diatomaceous, naturally cemented clays with alternating seams of fine sands and silty sands stratum. The results revealed that the installation technique of vertical gravel elements and the soil matrix affect the ultimate bearing capacity, deformation modulus, and stiffness of the vertical elements, as well as the geotechnical properties of the soil matrix
