Study of soils from two trenches opened in a slope of the Serra do Mar for the sliding analysis

Resumo

The landslides are mass gravitational movements induced by gravitational force and by the action of water. This event is the most recurrent and the largest producer of damages in Brazil. The objective of this research was to characterize soils from two trenches opened in a slope ot the Serra do Mar susceptible to landslides. Soil samples were collected and submitted to the geotechnical and physicoqchemical tests, which followed the Brazilian standards. A micro aggregation of the soil from both trenches was found on the basis of the granulometry analysis performed with and without deflocculant.
