ABSTRACT: This contribution presents a brief state of the art on the geotechnical characterization of Mexico City subsoil. Since the pioneer works by Carrillo, Marsal and Zeevaert, substantial progress has been achieved based on data obtained during the development of the infrastructure of this huge city. Following the dramatic 1985 earthquake, important field and laboratory research works have been performed on the very special properties of Mexico City lacustrine clays in static and dynamic conditions. Experience regarding foundations and underground structures behaviour has also been accumulating. Geographic Information Systems for geotechnical borings, hydraulic conditions and other aspects such as subsidence and soil fracturing are now available. This information has been organized and processed to develop 1D, 2D and 3D models of different parts of Mexico City valley. This has been useful to provide preliminary geotechnical information for new projects and to update the geotechnical zoning map included in Mexico City building code.

RESUMEN: En este trabajo se evalúa brevemente el estado actual de la caracterización del subsuelo del valle de la ciudad de México. Desde los trabajos pioneros de Carrillo, Marsal y Zeevaert, se han logrado avances significativos gracias a la información obtenida durante el desarrollo de la infraestructura de esta enorme ciudad. Después del dramático sismo de 1985, se han realizado múltiples trabajos de investigación de laboratorio y de campo respecto a las muy especiales propiedades de las arcillas lacustres de la Ciudad de México en condiciones estáticas y dinámicas. Experiencias relativas al comportamiento de cimentaciones y estructuras subterráneas se han ido también acumulando. Sistemas de información relativos a sondeos geotécnicos, a las condiciones hidráulicas y otros aspectos tales como la subsidencia y el fracturamiento del subsuelo se encuentran actualmente disponibles. Se ha realizado un esfuerzo sistemático para organizar y procesar esta información y para desarrollar modelos uni, bi y tri dimensionales del subsuelo de diferentes zonas del valle de México. Esto ha resultado de gran utilidad para disponer de información preliminar para nuevos proyectos y para actualizar la zonificación geotécnica del Reglamento de Construcciones de la Ciudad de México.
