Soluções para contenção de encostas em áreas com restrição de espaço para sua execução: um estudo de caso

Abstract

The present paper had the purpose of evaluating the execution of retaining structures in the construction works of an industrial warehouse measuring 3,000m² of constructed area, on a plot of land of 17,000 m², on a slope, limiting neighboring plots and the BA-526 highway, located on the mentioned highway, in the city of Salvador, Bahia. In order to evaluate possible technical solutions for the retaining structures in the area, object of this study, in a location of difficult access for its execution, topographical surveys and geotechnical investigations were performed, by means of percussion drilling and soil sample analysis, technological control of soil, detailed engineering design and specific contention projects, consulting with geotechnical specialists and monitoring by engineers for the execution of the works. After these analyses, the solutions found for the type of soil were soil nailing, gabion and projected hydroseeding, in order to maintain the desired stability with greater safety during execution. It was concluded that the chosen and jointly executed techniques were not very economic but had technical advantages regarding durability and safety, in relation to the other techniques analyzed.
