Identificación de materiales de mejoramiento en suelos expansivos destinados como suelo de fundación para viviendas en el sector Nor-Oriental de la ciudad de Tunja

Abstract

The research topic leads to establishing by identifying the characteristics of the materials, the behavior that they may present at the level of deformability, this due to that the north-eastern sector from the city of Tunja, it has the presence of clay levels that with the contact to the water present important conditions of expansion, with the purpose of know the most optimal method of stabilization that ensure a control of the deformations, before, during and after of the construction of a building of low category in the study sector, which is found localized in the north-eastern sector from the city, more specifically in the area between the campus of the Santo Tomas University, and the sports campus of the Boyacá University, over the University Avenue.

The activities to be developed in this document refer initially to the analysis of preliminary information, which includes laboratory results to samples from existing explorations, where they show the expansive behavior of the soil in the sector; where, once this situation has been identified, the geotechnical exploration is carried out, and subsequently, by means of laboratory tests, the material and the appropriate dosage are determined, which guarantees a significant reduction in the condition of the soil's expansiveness.

The present investigation involves to the sector North Avenue - University Villa, given that it is a zone that is found in growth. In bibliographic resources, reports were found that register structural damages to homes in the sector that didn't count with a previous improvement of the soils found there, whereby have been presented various situations in the development of civil works: how an unsuitable proposal in its foundation system, where elements are designed that aren't compatible with the characteristics of the material; equally exist cases of homes that with short time of use present structural failures to the improper use of the foundation systems.
