Development and application of construction monitoring system for super high-rise buildings

As the quick development of large structure, the work efficiency and measuring range of traditional monitoring method can not satisfy the needs of construction safety. Construction safety of a lot of code-defiant super high-rise structures lack the support of measured data. It's necessary to investigate the construction monitoring system for large structures. Base on the Kingkey Financial Center project, a comprehensive investigation of construction monitoring system for super high-rise buildings was conducted. The technology of full-process analysis of construction was used for optimal sensor placement. A proper layout program of temperature, vertical deformation and stress sensors was done according to the response of structure obtained by full-process analysis of construction. The sensors and hardware system were chosen considering their autologous characteristics and influence factors of lectotype. A software system for construction monitoring of super high-rise buildings was developed using Labview. The technology of wireless transmission was used in the monitoring system and a wireless data transmission scheme of distributed network was done to transmit real-time data on the construction site. Finally, construction monitoring system established on the construction site of the Kingkey Financial Center was finished with proper installation procedure and safeguard. The spot data collecting was also done. The analysis of the collected data shows that the system works reliably and tendency of the data is obvious. The system can obtain the temperature rule of structure dependent on the changes of sunshine and seasons and the response of structure during construction, providing the basis for knowing the state of structure during construction and making engineering measures. Furthermore, the installation and running of the system can also provide reference for similar building construction monitoring system of high integration and automatization of large structures.
