Internet of Things based Construction and Health Monitoring of High-pier Long-span Continuous Rigid Frame Bridge

This paper studies the network system framework of construction and health monitoring for high-pier long-span continuous steel bridges based on the Internet of Things. First, use midas/civil to establish a finite element analysis model, perform construction simulation calculations, study the changes in the stress and deflection of the main beam during the maximum cantilever state, mid-span closing, and ten-year shrinkage and creep, and determine the key control The cross-section and control parameters provide a theoretical basis for the framework of the health monitoring network system; secondly, combining the theoretical analysis results of the Wen tang Bridge, the construction monitoring status and integrating it into the health monitoring system, the integration of sensor distribution, software equipment, and information technology is proposed Designed and established a complete network system framework for construction and health monitoring of high-pier and large-span continuous steel bridges. The application of Internet of Things technology to bridge monitoring (control) realizes the effectiveness and intelligence of bridge monitoring (control) information, and ensures the safety and reliability of the bridge structure.
