Construction Process Monitoring of CCTV Main Building Structure in China

The main building of CCTV (China Central Television) new site project consists of two leaning towers, which are linked together at the top via a large cantilever link element. During construction of the tower, it has the particularity in deformation of the structure and stress state of components, consequently, the safety control of the structure in the construction process is very important. The monitoring techniques and results are introduced, including the foundation settlement, the main structure stress, the structure deformation, and the cantilever deformation. The applications of monitoring and simulation analysis technologies in the construction process provide data support and guarantee the construction safety of the CCTV main building.
