Measurement Technology of Steel Structure in Guangzhou New TV Tower

广州新电视塔钢结构形体特殊,空间通视条件差,且构件均为空间三维倾斜,对测量工作提出了很高要求。同时由于其高而纤细的形体,施工过程中受日照和焊接影响非常显著,期间会产生较大的不可忽略的变形,这些因素都对测量工作产生极为不利的影响。通过采用双重测量控制网、高精度测量仪器,及时监控结构变形,有效控制测量过程,顺利完成广州新电视塔钢结构的测量工作。

The steel structure is with special shape, had visual conditions and three-dimensional oblique members in Guangzhou New TV Tower, which put forward high requestments to measurement work. Then, high and thin shape is affected by sunshine and welding to produce bigger deformation. These factors can bring unfavorable influences on measurement. Structure deformation is monitored by double surveying centrol network and high precision machines to control effectively the process of measurement. The measurement work of steel structure is sueeessfully cempleted in Guangzhou New TV Tower.
