对于索穹顶等预应力结构,在张拉施工时,需要保证结构的正确成型与合理受力,有必要进行实时的施工过程监测。以中国煤炭交易中心索穹顶为例,阐述了结构监测系统的组成,确定了监测方式和相关监测内容,进行了索穹顶的应力、位移和索力的施工过程监测。监测数据分析结果表明结构施工完后符合设计要求。
For prestressed cable domes and other structures, the tension in the construction, the need to ensure the correct structure and reasonable force, it is necessary for real-time monitoring of the construction process. Taking the cable dome of China Coal Trading Center as an example, the composition of the structure monitoring system is expounded, the monitoring methods and related monitoring contents are determined, and the construction process monitoring of cable domes’ stress, displacement and cable force is conducted. The monitoring data analysis results show that the structure meets the design requirements after construction.
