Abstract
During the construction of the three-arm arc-shaped working gate in service,the supporting arm was deformed and damaged due to accidents,After correction,repair and reinforcement,it has operated normally for more than 20 years.The gate is related to the safety of the spillway and the safety of the whole project.In order to analyze the safety performance of the gate,combined with the deformation of the reinforcement part of the support arm,the strength and stability of the support arm of the gate are checked and calculated.The comprehensive analysis results show that the strength and stability of the arm meet the specification requirements.It provides reference for the maintenance and overhaul of similar engineering metal structures,and also provides technical basis for the follow-up measurement of the stress of each component of the gate.关键词
