Evaluación geotécnica preliminar de las unidadesgeológicas del frente costero portuario de Bahía Blanca, Buenos Aires, Argentina

Bahía Blanca is located in the province of Buenos Aires (Argentina) and is the urban center with the greatest development inthe southwest of Buenos Aires. It has a deep water port, enabling national and international commercial flow. Currently one ofthe most recurrent problems is the expansion of cities without land use guidelines, evidenced in the study area by the occupationof spaces on expansive materials, reactive to changes in soil moisture and consequent failures in foundations, structural damageand economic losses.The study area includes the waterfront of the city of Bahía Blanca and its projection towards the interior of the estuary,extending from the port of Ingeniero White to the locality of Daniel Cerri. The objective of the study is a preliminary evaluationat a generic and qualitative level of the geological and geotechnical characteristics and the relationship between them.Outcropping and subsoil geological units are recognized and qualified according to the geotechnical response of the materials,based on existing information. The sediments that constitute the support of the works are identified and characterized andparameters and characteristics that influence their geotechnical response and possible instability of the constructions are defined.This research proposes to formulate guidelines that promote a rational territorial ordering, in accordance with the geological andgeomechanical characteristics of the land, determining its possible uses. The results will be applied to mitigate or avoid geologicalrisks and contribute to the sustainable development of an area in commercial and economic expansion, which promotes thelocation of industrial, port and urban infrastructure Bahía Blanca está ubicada en la provincia de Buenos Aires (Argentina) y es el centro urbano con mayor desarrollo del suroeste bonaerense. Cuenta con un puerto de aguas profundas, posibilitando el flujo comercial nacional e internacional .Actualmente una de las problemáticas más recurrentes es la expansión de las ciudades sin pautas de ordenamiento territorial, evidenciada en el área de estudio por la ocupación de espacios sobre materiales expansivos, reactivos a cambios de humedad del suelo y consecuentes fallas en fundaciones, daños estructurales y pérdidas económicas. El área de estudio comprende el frente costero de la ciudad de Bahía Blanca y su proyección hacia el interior del estuario ,extendiéndose desde el puerto de Ingeniero White hasta la localidad Daniel Cerri.
