Análise das manifestações patológicas em contenções de solo reforçado: um estudo de caso em viadutos da região metropolitana de João Pessoa - PB

Abstract

Reinforced soil structures are widely used in civil engineering and are essential for the safety and functionality of works such as viaducts. Careful execution of these structures is fundamental to minimize the occurrence of pathological manifestations, which, if left untreated, can result in significant damage and high repair costs. This study analyzes six viaducts in the Metropolitan Region of João Pessoa, of which five have been completed and in operation for several years, and one is still under construction. The aim is to identify issues in the existing structures, such as cracks, corrosion of reinforcements, and construction flaws, and to evaluate the corrective and preventive measures adopted in the ongoing work to avoid the recurrence of these pathologies. The research includes visual inspections, analysis of technical documentation, and discussions with professionals involved in the ongoing construction, allowing for a comprehensive understan ding of the conditions of the structures. The results indicate that prompt recovery of pathologies is important not only to avoid costly interventions but also to ensure user safety and the integrity of the infrastructures. Inadequate maintenance can lead to serious consequences, including risks to urban mobility and human life. Finally, recommendations are presented to improve the conservation, performance, and lifespan of reinforced soil walls, emphasizing the importance of proactive management in maintaining these works. The implementation of a continuous monitoring plan and the training of technical teams are suggested as essential measures to ensure the effectiveness of the reinforcements and promote the long-term durability of the structures
