A Estabilidade dos Taludes e Suas Implicações Socioeconômicas: Uma Análise do Maior Desastre Natural do Brasil

Abstract

The objective of this academic work is to analyze the case of landslides that occurred in 2011 in the state of Rio de Janeiro, caused not only by heavy rainfall but also because of the rains accumulated in the days leading up to the tragedy, As will be shown in the relevant chapter. It will be seen in this paper the socioeconomic impacts of landslides in the Serrana region of Rio de Janeiro, the site of the largest natural disaster in Brazil. The influence of climate, relief, geology, pluviometry, among other topics will be brought to a reflection in order to bring light, from the point of view of civil engineering, of what solutions could be given so that the impacts caused by landslides were placated . More than 900 deaths, 50,000 homeless, 150 missing and about one million people who, directly or indirectly, were affected by the tragedy, expect from technology a plausible solution for this region that, not infrequently, suffers from landslides. Particular attention will be paid to rainfall, which is the main triggering agent of non-anthropic landslides. Among the anthropic agents, the irregular occupation and modification of the inclination of the slopes will be very remembered. Particular characteristics of the mass movements that have occurred will be studied here in a way that understands what engineering knows about the subject and what answers can be given. The demonstration of how soil slides occurred can affect the lives of people living in the region, the environmental impacts and the close relationship with the economy are greater than you can imagine. Proof said it is that five years after the tragedy still has sequels on the economy that begin to be overcome.
