CARACTERIZACIÓN GEOESTADÍSTICA DEL SUBSUELO DEL EX-LAGO DE TEXCOCO

Abstract

In this paper a brief description about geotechnical characteristics of ex-Texcoco lake subsoil is presented. The description is based in physic and geographic information and particularly in geotechnical borings information. This information is integrated using a Geographic Information System. For other hand, the spatial distribution of typical layers subsoil is made using geostatistical techniques, as result, a set of contour maps of depth and thickness of typical layers subsoil is presented. Also, some examples of analyses of spatial distribution of soil properties (water content and resistance of cone penetration test) along of preferential axes are presented. A 3D model for typical layers subsoil is made using advanced tools for plotting. Also, some examples of multivariate geostatistical are presented. This examples show as the Cokriging techniques allow to get estimates of one soil property from the data of same property and other one of different type but both correlated. As result, a detailed geotechnical zoning map for ex Texcoco Lake subsoil and their influence areas is presented.
