Avaliação do impacto de barreiras físico-naturais no traçado de ferrovias: o caso da barragem Serro Azul na implantação da ferrovia Nova Transnordestina

Abstract

This work aims to evaluate the influence of dam construction Serro Azul deployment Railroad New Transnordestina the interior of Pernambuco , comparing the originally proposed route to the proposition made by the designers due to the presence of physicalnatural barrier imposed on the original path . After the lease to private initiative of the Brazilian rail network, 16 years of operation for the railway had key role again in the national logistics were needed. Over the past few years , there was a gradual growth in cargo handling by this industry , proving to be the most efficient means of land transport and feasible to move large volumes of cargo. Thus, the federal government has encouraged the establishment of new rail segments in the country, and the New Train Transnordestina is considered large investment in the sector and with great social potential for the region. However, this design suffers from interference from physical and natural barriers, which has forced the revision of the trace. This fact motivated the execution of this work, the method compares the alternatives presented in the light of changes in earthmoving services, specifically in the volume of earth movement, in order to enable a decision about this new condition imposed on rail Project.
