Análisis de las propiedades geotécnicas del subsuelo del polígono 2 frente a la estimación de carga para edificaciones

Abstract

Abstract: The objective of this study is to evaluate the geotechnical properties of the subsoil of Polygon 2 to estimate the appropriate load-bearing capacity for buildings and prevent structural failures. The research is based on the analysis of a pre-existing database of SPT tests performed at different locations within Polygon 2, which includes information on bearing capacity, SUCS soil classification, friction angle, cohesion, specific gravity, and depth of deposition. Empirical correlations were used to estimate the missing geomechanical properties necessary for accurate simulation of soil behavior in PLAXIS 3D. Building loads were estimated considering two types of occupancy: residential and special uses (commercial, restaurants, gyms), with heights ranging from one to five stories. The maximum number of floors that can be built at each point was determined using isolated square footings measuring 1 m on each side without exceeding the permissible settlement limits. In cases where these limits were exceeded, foundation design recommendations were proposed in accordance with the Ecuadorian Construction Code (NEC) and ACI 318-14, successfully controlling settlements within acceptable limits.
