摘要
体育场作为重要的公共建筑,其安全可靠性至关重要。TM30全站仪是一款具有ART功能、小视场技术的高精度测量仪器。本文通过建立独立坐标系统,安置固定监测点标志,使用TM30全站仪,采用精密三维坐标法监测体育场主桁架结构在温度影响下的变形量,并对监测数据进行分析。结果表明利用TM30全站仪采用精密三维坐标法能够满足体育场结构变形监测的精度要求,并具有可靠、简便、高效的优点,为今后类似工程的变形监测积累了经验。
The stadium is an important public building, of which its safety and reliability are essential. TM30 total station is a high-precision measuring instrument with ART function and small field technology. In this paper, through the establishment of independent coordinate system and the location of fixed monitoring point mark, TM30 total station is used to monitor the deformation of the main truss structure under the influence of temperature by precision three-dimensional coordinate method, and the monitoring data are analyzed. The result shows that the precision three-dimensional coordinate method can meet the accuracy requirements of the deformation monitoring of the stadium, which has the advantages of reliable, simple and efficient, and accumulates experience for the future deformation monitoring of similar projects.
