Análise paramétrica da estabilidade de um talude

Abstract

Road transport in Brazil is the main logistics system. Obstruction of some highway due to natural causes is a problem that often occurs. It is essential to know methods that can stabilize slopes, in particular road ones. This study aims to evaluate the stability of a road slope, located in Queluz in São Paulo, through established methods proposed by: Bishop, Spencer and Fellenius. The analysis is first made by changes in resistant and external parameters surrounding the slope under study. Among the many parameters to consider this work covered cohesion, specific weight, friction angle, water level and overcharge on the slope. The studies were analyzed using the software developed by Rocscience called Slide, version 6.0. After the variations it was found that the most influential parameters in the slope stability were cohesion and angle of friction. Thus the greater the resistance will be smaller soil costs reinforcing elements, becoming of such importance the correct determination of the geotechnical data of the profile.
