Resumen
The geotechnical grouping investigation by SPT and SCP, following the criteria of geologic-environmental factor influences, allows identifying influence zones of soils maturation stage and domain areas of different geomorphological conditions. These groups were identified from the location of investigations in maps, verifying different behaviors of the qc/N reason, in each considered domain. The current study describes the criteria utilized in this differentiation, presenting the correlation between qc and N and diagrams showing the behavior of the K (qc/N) in relation to the depth, considering the results found.
