Geological-geotechnical chacterization and engineering solutions for erosion stabilizatin in Suzigan Stream

Abstract:

The gully on Suzigan creek spring, located on the border of the municipalities of Santa Barbara d’Oeste and Americana (SP), achieved approximately 600 m on length, with a width varying between 20 m and 150 m, with slopes up to 80 degrees and heights between 5 m and 21 m. The process reached urban areas in NW/SE direction and triggered significant productive areas losses in its surroundings, besides causing major silting downstream, in the Piracicaba river. This paper presents the results of the geological-geotechnical/hydrological studies carried out by IPT in the area and the engineering solutions that were needed to stabilize the erosive process following the pre-established premises: rainwater should be conducted on an open channel; the slopes should be stabilized minimizing productive area losses; the original topography of erosive process ramifications must be recovered; the entire cut-off volume required for stabilization of the erosive process should be disposed on compacted landfills inside the gully.
