Taking the maintenance and reinforcement project of a T-shaped truss beam bridge in Wuhan as the back-ground,the current situation and disease situation of the bridge were introduced.Based on the maintenance and rein-forcement objectives,reinforcement measures such as dismantling the original hanging hole concrete T-beams,replacing them with I-shaped steel plate composite beams,and pasting steel plates to reinforce the brackets have been formula-ted,reducing the dead load of the bridge structure and enhancing the structural safety performance of the bridge.Bridge construction monitoring can achieve 24-hour uninterrupted stress monitoring,and measured values were far less than theoretical values to ensure structural safety during the construction.
