Résumé:
This article presents a detailed study of the geotechnical characteristics of Oxiosols and
Argisols, two types of soils widely found in various Brazilian regions. The main objective was
to analyze the literature that investigates these soils and the SPT and CPT methods.
Latosols and Argisols are highly weathered tropical soils that play a fundamental role in
agriculture and civil engineering. Understanding their geotechnical properties is crucial for
the planning and execution of structors. The SPT is a standard penetration test that
measures the soil's resistance along a specific depth. It provides information about
compaction, relative density, shear strength, and
soil-bearing capacity. On the other hand, the CPT utilizes a cone penetrometer to measure
soil resistance, consistency, permeability, and behavior during penetration. This study was
conducted to analyze and compare the viewpoints of 15 authors on these topics and their
relevance to the geotechnical field. The literature review focused on understanding the
geotechnical properties of Latosols and Argisols and the application of SPT and CPT
methods to the civil construction area and the impact about the foundations construction.
