【Abstract】 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.更多还原
