Analysis and Solution of Containment Stabilization in Gabions Held at the BR-060 Margins in the Municipality of Guapó/Goiás, Brazil

Abstract

This work presents the rupture in a road cut slope with an approximate extension of 100 m, located on the banks of the BR-060 in the urban stretch of the municipality of Guapó/GO. The studies consisted in the execution of a program of field incursions to verify the geotechnical conditions in the indicated section, collection of soil samples, execution of laboratory tests, analysis of slope stabilities and the consequent proposition of stabilization using the structure of containment in gabions of 6.0 m height, 2: 1 slope (H: V) and subsequent planting of grass with protection against surface erosion. The solution adopted in gabions to contain the damaged section proved to be advantageous, considering the economic aspect of other solutions, and its executive simplicity provided speed to the executive process, allowing execution in the rainy season without any kind of intercurrence. In order to verify the current conditions of the implanted system, a visit was made at the beginning of 2017 to the place where the intervention took place and it was found that the implanted works are consistent with the expected operation.
