Modelación numérica geotécnica – estructural de una vivienda unifamiliar, aplicando un método de recalce de cimentación, limitando los asentamientos diferenciales

Abstract

Due to the inconveniences observed in the infrastructures that have been affected by the excessive settlements in the southern zone of the Metropolitan District of Quito, in the sector of Solanda, which were caused by the type of soil, the informality of the constructions and other factors, this problem was considered as a case study. Therefore, the purpose of this project was to perform the geotechnical-structural analysis of a house, through a simulated numerical model in different stages, using the MIDAS GTS NX software, which yielded results that allowed understanding the soil-structure behavior, identifying the foundations affected by the existing problem, verifying that these data resemble reality and starting from these, implement a method of underlining which consists of the use of micropiles. For this, the calculation of its pre-design was carried out, taking into account the parameters of the soil and the material that constitutes this structural element. Once this method of underpinning was applied through the modeling of its construction process and implementation in the foundations that need additional support to resist and transmit the service loads to a more stable soil, it was possible to verify that the value of the settlements decreased, being within the permissible ranges established by the Norma Ecuatoriana de la Construcción (NEC-15), being the most optimal and viable solution to mitigate the effects caused by the problems described.
