Uso de perfis metálicos aplicados em estrutura de contenção

Abstract

In geotechnical works involving excavation activities—whether in the construction of transportation routes, hydraulic channels, or buildings—the implementation of retaining structures to resist earth pressure and prevent the movement of soil masses, ensuring safety, is a widely used and historically ancient technique. Although ancient, the use of these techniques has undergone modernization throughout human development, alongside the emergence of new technologies and equipment, resulting in a wide variety of retaining structure mechanisms available in the current market. One such technique is the installation of steel profiles used in retaining walls and sheet pile walls, characterized by speed, efficiency, and, when properly executed, safety—factors that justify the extensive use of retaining structures made of precast concrete and steel profiles. This undergraduate thesis aims to present a bibliographic review and a field experimental study on the use of steel profiles in retaining structures, addressing a brief historical background, the steel production process of the profiles, the physical and chemical properties that compose these elements, their applications, advantages, disadvantages, and execution process. After the completion of the literature review and the monitoring of a project involving the installation of these profiles in a retaining structure, a technical manuscript will be produced and made available to students of civil engineering, transportation engineering, and professionals in the field for consultation in their professional development.
