Fundações profundas: viabilidade técnica e econômica para um estudo de caso localizado em Ponte Nova – MG

Abstract

Foundations are generally classified into two main categories: shallow and deep. The selection of the appropriate foundation type is determined by the magnitude of the structural loads and the bearing capacity of the underlying soil. In this study, which focuses on an eight-story building characterized by substantial load demands, three deep foundation systems were evaluated to assess their technical and economic feasibility. Each system was analyzed in detail, including a comprehensive characterization of the site conditions and the structural loads involved. Subsequently, the design parameters for each foundation type were developed, followed by a cost estimation for implementation. The findings indicate that, for the specific conditions of the case study located in Ponte Nova, Minas Gerais, the continuous flight auger (CFA) pile system presented the most favorable balance between performance and cost-effectiveness.
