Inspeção de pontes na cidade de Jataí-GO

Abstract

This study aimed to inspect special engineering structures located in the municipality of Jataí, Goiás, focusing on the assessment of the structural, functional and durability conditions of urban bridges and small bridges. The research was developed through a literature review on bridge inspection, conservation and pathological manifestations, combined with the application of cadastral and routine inspection forms based on the guidelines of ABNT NBR 9452:2023 and DNIT 010/2004 PRO. Nine special engineering structures were evaluated through visual inspections, photographic records, basic geometric measurements and identification of the main anomalies observed in structural and functional elements. The results indicated the recurrent occurrence of drainage failures, erosive processes, silting, accumulation of solid waste, reinforcement corrosion, leaching, efflorescence, deterioration of guardrails and accessibility deficiencies for pedestrians. Among the inspected structures, some showed preserved global stability, while others required priority interventions, especially in cases involving scour, collapse of retaining elements and compromised safety devices. It is concluded that the systematization of inspections contributes to the identification of maintenance priorities and supports municipal management in decision-making processes aimed at conservation, safety and extension of the service life of the evaluated bridges.
