Intelligent Monitoring Technologies Used in Rotation Construction of Bridges over Live Railways Based on Cloud Monitoring Platform
A smart rotation construction monitoring system for bridges over live railways is presented,which integrates multiple new-generation digital technologies,including digital twin,combination of BIM and GIS,intelligent sensing,internet of things,edge computing,and cloud computing,etc.to achieve the real-time monitoring of the construction process and improve the rotation efficiency and accuracy.The system is able to conduct real-time monitoring of the environmental parameters,rotation parameters,and structural stresses,and simulate the rotation process as well,thus achieving the expected intelligent sensing,analysis and early warning,and visualization throughout the whole rotation construction process of the bridge.With the real-time 3D coordinates of the ends of the cantilever rotated,the formulas to calculate the rotation angle,angular velocity and rotation distance are created,which are considered reflecting the real rotation performance.To address the linkage monitoring of the rotation of two parallel superstructures,formulas to calculate the proper spacing of the left and right superstructures are given.The presented system has been applied in several bridge projects,helping realize the efficient rotation and high-precision positioning of the structures rotated.
