Caracterização de solo de talude da CE-356 - análise de estabilidade

Abstract

In Brazil, most cargo transport is done by road, which makes the economy dependent on its proper functioning. This dependence, added to the continental size of the country, contributed to the existence of an extensive road network. Works involving geotechnical engineering must be studied carefully to ensure their safety, especially in the area of analyzing the stability of road embankments. Due to the intense vehicle traffic, any failure in the embankments of these roads, such as falling debris or slipping, can lead to loss of human life, impacts on the environment and economic losses. Many of these accidents could be avoided or reduced if there were more studies on the stability of road slopes. In view of this, this work aims to analyze the stability of a slope in the stretch of CE-356 that connects Russas/CE to Baraúna/RN, also known as "Estrada da Fruta". For this, the characterization of a soil sample from the slope was carried out. Soon after the material was characterized, the slope stability analysis was performed in the SLOPE/W software, with the objective of verifying the safety factor. Simulations were tested for the following analysis methods: Fellenius, Bishop, Janbu, Spencer and Morgenstern-Price. After a comparison between the results, it was found that four of the five methods presented a FS above “1.5”, confirming the stability and safety on the studied slope.
