【摘要】 针对实际运营环境及结构受力情况建立了某大型单拱肋中承式钢拱桥的在线监测系统,并以监测数据为基础,初步分析了结构的应变、加速度及环境温湿度变化情况,为同类桥梁结构的受力分析及运营实桥结构在线健康监测系统的实践应用提供参考。更多还原

【Abstract】 According to the actual operating environment and structural stress condition, the online structural monitoring system is established on a half-through steel arch bridge with single arch face. On the basis of monitoring records, the data of the strain, acceleration, temperature and humidity are preliminarily analyzed. The system establishing practice and test data analysis could provide effective references to structural analysis of similar bridge and practical application of the structural online monitoring system.更多还原
