摘　　要：在大跨度钢结构的吊装施工过程中,易发生工程事故。而传统的监测方法适用范围小,难以协调监测和控制施工,会导致出现许多问题,基于此,建立大跨度钢结构多点吊装结构监测方法。通过采集监测数据,实时输出大跨度钢度结构的挠度、应力、应变、风力和温度等,实现实时监测,确保吊装过程的安全。试验结果表明,对大跨度钢结构进行复合监测可以实现实时监测,且已知最大变形均发生在大跨度钢结构的中线处;人工检测与实时结构监测系统误差范围较小,平均值为2.1%。During the hoisting construction process of large-span steel structures,engineering accidents are prone to occur.However,traditional monitoring methods have a limited scope of application and are difficult to coordinate monitoring and control construction,which can lead to many problems.Based on this,a monitoring method for multi-point lifting structures of large-span steel structures is established.By collecting monitoring data and outputting real-time deflection,stress,strain,wind force,and temperature of large-span steel structures,real-time monitoring is achieved to ensure the safety of the lifting process.The experimental results indicate that composite monitoring of large-span steel structures can achieve real-time monitoring.And it is known that the maximum deformation occurs at the centerline of the large-span steel structure.The error range of manual detection and real-time structural monitoring system is relatively small,with an average value of 2.1%.
