Abstract

The Colombian territory is divided geographically in regions that present display own characteristics as far as relief, climate, vegetation and geology, that offer an ample supply of grounds with properties dissimilar mechanical indices and. The professional exercise of geotecnia requires of a detailed methodology for the geotechnical design of the layings of foundations, consequent with the nature and properties of grounds in the country, and that as well, guarantees a process of safe and rational calculation.
It is required of geotechnical investigations that allow to know the properties physical the subsoil, their properties of resistance to the shearing strain, deformation and compressibility before static loads, like his behavior before dynamic loads. The use of codes and the mechanical physical characterization of the materials the information and the experience between the engineers make possible sharing, and inclusively it allows to compile information of common utility, like the geotechnical microzonings.
Until it does few decades, the geotecnistas engineers only applied to the mechanics and the hydraulics to face the complex problems of the practice, and by means of the use of bad calls “you formulate classic”. These, by means of the use of a determinístico total factor of safety, have allowed adapting and providing relation between the resistance of the subsoil and the system chosen for the transmission of the loads of a construction, with a safety margin adapted of stability. National Engineering requires of codes like norma sismo resistente 2010 –NSR10, based on the model of states design limit, where from the beginning of structured design with rules of associated application, allow to determine the proportions the layings of foundations with own levels of security of the country.
