Estudo exploratório para implantação de campo experimental em pedreira desativada no município de Toledo - PR

Abstract

The geotechnical analysis of the subsoil is essential to ensure the stability and safety of civil engineering works. In this context, this study was developed to contribute to the characterization of the subsoil and the improvement of geotechnical investigation methods in the Toledo-PR region. Field surveys and exploratory tests were conducted, including tactile-visual analysis, to identify the characteristics of the soil and local rock formations. The results indicated that the region has a predominantly rocky subsoil, with thin layers of residual soil and a strong influence from basaltic formations. The application of the SPT test proved to be limited for conventional investigations, while rotary drilling demonstrated greater efficiency in characterizing the rock and studying deep foundations. The stability of slopes was assessed, highlighting the need for complementary studies to analyze shear strength and the durability of reinforcement solutions, especially in areas exposed to weathering. The creation of an experimental f ield in the deactivated quarry could represent a significant advancement in geotechnical engineering research, providing a controlled environment for tests and trials that help in understanding the mechanical behavior of local rocks and soils. Moreover, this initiative could benefit both the academic community and the construction sector, contributing to the improvement of construction techniques and the implementation of safer and more sustainable solutions.
