Comparación de metodologías de análisis en el diseño geotécnico-estructural de cimentaciones superficiales en depósitos con suelos blandos.

Abstract

Most of the structures in Guayaquil city are founded in a landfill of soft soil deposits. The foundation is the most important element of construction cause it transfers loads of the structure to the ground thats why it is necessary to do an adequate analysis that will results in a more economical and safe design. A large part of structures are designed by assuming rigid foundation without considering the flexibility of soil. The lack of knowledge when considering the rigidity of the soil may estimates unreal values of forces, moments, settlements, etc. The present study, is going to compare qualitative and quantitave results obtained by three geotechnical-structural design methodologies for the analysis of shallow foundations such as:  Conventional Method using ACI 318-14 criteria and assuming an uniform distribution of the Soil  Winkler Method determined that the soil below the foundation is formed by independent elastic springs using modulus of subgrade reaction (k)  Finite Elements Analysis: using constitutive models through 3D PLAXIS The comparison of theses three methodologies will help in having others approaches in differents projects according to its characteristics and soil conditions.
