摘　　要：针对承受超重荷载施工挂篮使用过程中荷载工况复杂,结构失效造成后果严重,人工监测难以满足复杂条件下挂篮监控数据的及时反馈,也难以完成恶劣天气下对挂篮的监测,采用桥梁挂篮自动化监控系统,并通过预压方式检验自动化监控系统可靠性。结果表明:桥梁挂篮自动化监控系统应力、位移数据发展趋势与加载工况一致,系统位移自动监测值基本介于人工监测值与有限元计算值之间,系统吊带应力实测均值与理论计算值、有限元计算值均较接近。In view of the complex load conditions and serious consequences caused by structural failure during the use of the construction hanging basket under overload,manual monitoring is difficult to meet the timely feedback of the hanging basket monitoring data under complex conditions,and it is difficult to complete the monitoring of the hanging basket in bad weather,the automatic monitoring system of the bridge hanging basket is adopted,and the reliability of the automatic monitoring system is checked by preloading.The results show that the development trend of the stress and displacement data of the automatic monitoring system of the bridge hanging basket is consistent with the loading conditions,the automatic monitoring value of the system displacement is basically between the manual monitoring value and the finite element calculation value,and the measured mean stress of the system sling is close to the theoretical calculation value and the finite element calculation value.
