Soluções de reforço e recuperação de solos em processos erosivos urbanos em Aparecida de Goiânia

Abstract

Controlling erosion has become a big challenge for urban centers around the world. In Aparecida de Goiânia it is no different because it has several streams in the urban area. Thus, there is a need to protect soil near the streams to prevent erosive processes. Several factors can trigger the erosive process and Civil Engineering has technical solutions to solve these problems. This research presents a case study of an erosive process located in Aparecida de Goiânia, near the Córrego do Açude and suggests two technical solutions for the case. The first solution proposes removing the houses close to the erosion and the other proposal considers keeping the houses in order to make the recovery of the degraded area. The proposals are compared technically considering the main quantitative material and services of each one. The research’s results include the development of a containment project in gabion and Reno, mattress considering two solutions by transversal cuts to the creek in relation to the lots of the residences, longitudinal cut to the oil of the creek and the technical version of the proposals. In addition, a survey performs slope stability and containment analyzes. The safety factors obtained in these analyzes have been satisfactory. In cases of obtaining high-security factors, it is suggested a possibility of resizing to obtain a more economical structure without compromising a security of the structure.
