SANCHEZ ARREDONDO, LUÍS HERNÁN  and  RAMIREZ BOLIVAR, GLORIA ISABEL. IMPLEMENTATION OF THE CONFIDENCE INTERVAL APPROACH AS GEOSTATISTICAL NONLINEAR MODELING FOR SPACE GEOTECHNICAL VARIABLES. Dyna rev.fac.nac.minas [online]. 2012, vol.79, n.173, pp.15-24. ISSN 0012-7353.

This study aimed to primary work computer mapping of some of the physical - rnechanical properties of soil in an area of Barrio Laureles -Medellín Colornbia. As the estimation method it was mainly used the geostatistical technique known as "confidence interval", which was developed by the Ecole des Mines de Paris. The database corresponds to one of geotechnical engineering firms in Medellin city, which have been collected between 1993 and 2005, extracting information related to the standard penetration tests NSPT, natural soil moisture and compressive Qu. For geostatistical data assessment were carried out exploratory stages of analysis, structural analysis; estimation, simulation, and implementation of the confidence interval. The confidence interval method is very useful for analyzing the statistical distribution of free variables, in this case it was able to identify any extreme values for the variables mentioned above

Keywords : Geostatistics; geotechnical; confidence interval; kriging.
