ABSTRACT: This paper presents recent advances in the geotechnical characterization of Mexico City subsoil based on a Geographic Information System for Geotechnical Borings (GIS-GB) that includes more than 7,000 soil profiles. Geostatistical techniques were used to define 2D and 3D models of the subsoil. Contours map of layers thickness, as well as index (water content) and mechanical (CPT point resistance) properties in the area were also obtained. The maps that have been established have been used in order to update the geotechnical zoning presented in Mexico City Building Code.

RESUMEN: En este trabajo se presenta una contribución a la caracterización del subsuelo de origen lacustre de la zona norte de la cuenca de México, a partir de los resultados de exploraciones geotécnicas. Se emplea la Geoestadística como herramienta para definir modelos 2D y 3D del subsuelo. Se han obtenido mapas de isovalores de espesores de estratos y de propiedades índice (contenido de agua) y mecánicas (resistencia de punta en pruebas de cono) para el área de estudio. Los mapas que se han construido se han usado para actualizar la zonificación geotécnica del Reglamento de Construcciones de la Ciudad de México.
