| description | The dynamic compaction method, very little spread in Argentina, has not been used in the city of Córdoba until this occasion. Its application in the “Bajo Grande Sewage Liquid Treatment Plant” has been a great technical and economic achievement. This article synthesizes geotechnical studies before the improvement, characterizes the dynamic compaction from the existing soil profile, and requirements of major works such as settlers and aeration tanks. Aspects of work control during its execution, data from soil studies after improvement, parameters of the mathematical model used to carry out the prognosis of seats according to the evaluated soil profile and measurements of validation of seats with the sedimentation tanks in operation are mentioned. Compaction was carried out by dropping a 10000 kg mass in free fall at a height of 15m from a crane, on points approximately 2.8 m apart. Two phases of several falls were executed allowing an increase in the relative density of the original soil to a maximum of 70%, reducing vertical settlements by 10%, decreasing angular distortion in half, doubling the bearing capacity, and reaching a maximum depth improvement near 6m. Then a ground leveling phase with mechanical compaction was carried out by project requirement. It could be concluded that the foundation of the construction with reinforced concrete stalls on the improved soil, presented a very superior technical-economic feasibility with respect to the alternative of a deep foundation with piles, which justified the execution of dynamic compaction in this work. |

El método de compactación dinámica, muy poco difundido en Argentina, no ha sido utilizado en la ciudad de Córdoba hasta esta ocasión. Su aplicación en la “Planta de Tratamiento de Líquidos Cloacales Bajo Grande” ha constituido un gran logro técnico y ecónomico. Este artículo sintetiza estudios geotécnicos previos al mejoramiento, caracteriza la compactación dinámica a partir del perfil de suelos existente y requisitos de obras de gran impronta como sedimentadores y tanques de aireación. Se mencionan aspectos de control de obra durante su ejecución, datos de estudios de suelos posteriores al mejoramiento, parámetros del modelo matemático empleado para efectuar la prognosis de asientos de acuerdo al perfil de suelos evaluado y mediciones de validación de asientos con los sedimentadores en funcionamiento. La compactación se llevó a cabo dejando caer una masa de 10000 kg en caída libre a 15 m de altura desde una grúa, sobre puntos distanciados aproximadamente a 2.8 m entre sí. Se ejecutaron dos fases de varias caídas permitiendo un aumento de la densidad relativa del suelo original hasta un máximo de 70%, reduciendo los asentamientos verticales 10%, disminuyendo la distorsión angular a la mitad, duplicando la capacidad portante y alcanzando una profundidad máxima de mejoramiento próxima a 6 m. Luego se realizó por requisito de proyecto una fase de nivelación de terreno con compactación mecánica. Pudo concluirse que la fundación de la obra con plateas de hormigón armado sobre el suelo mejorado, presentó una factibilidad técnica-económica muy superior respecto a la alternativa de una fundación profunda con pilotes, lo que justificó la ejecución de la compactación dinámica en esta obra.
