Aplicação do Ground Penetration Radar (GPR) na identificação de zonas anômalas por meio de uma metodologia de inovação com abordagens de produção enxuta

Abstract

To ensure safe lifting of loads with a crane, reliable information about subsurface strength is essential. Otherwise, equipment tipping can occur, resulting in not only material losses but also irreparable harm to the lives of employees involved in operations. The methodology employed in this study was developed by the organization under investigation and consists of four main stages: (i) Problem Identification, (ii) Conceptualization, (iii) Pilot Testing, and (iv) Implementation. Lean Six Sigma tools were used to analyze the problem throughout these stages. Among the potential areas explored were technologies related to probes, digital soil mapping, geotechnics, and equipment for stabilization. The chosen technology for on-site evaluation was Ground Penetration Radar (GPR), which effectively mapped the soil, identifying subsurface conditions and interferences in the selected test regions. GPR demonstrated 100% adherence to the established Key Performance Indicators (KPIs) for project validation.
