Modelagem e análise do reforço estrutural do Cais da Gamboa visando aprofundamento do berço de atracação

Abstract

It is through ports where most of the exports and imports of goods take place in Brazil. It is the increased demand for trade that arouses the need for port modernization, enabling larger vessels and larger capacity equipments to be able to operate in such facility. Therefore, aiming to accommodate larger ships, the present work deals with the structural reinforcement of the Gamboa Quay, in the Port of Rio de Janeiro (RJ), aiming at deepening the berth of the passenger terminal. The Gamboa Pier is a historic structure within the context of the city of Rio de Janeiro, and the reinforcement project aims to maintain this structure in its entirety, as well as not altering Guanabara Bay's water area, an environmental heritage site. This thesis seeks to bring all the history of the quay and show the evolution of the administration of Rio de Janeiro Port over the years. This work briefly presents a review on topics such as geotechnological investigations in the field of maritime works, their geotechnical aspects, and briefly discusses the dredging process. The structural reinforcement project modeling was performed using RS2 software by Canadian company Rocscience, using the Finite Element Method. Thus, the stability of the quay was analyzed through the Safety Factor of the work, observing results as maximum shear stresses developed by the massif and total displacement of the structure.
