为研究徕卡TS30超高精度全站仪自由设站法能够满足精密工程测量的要求,采用理论分析和工程实例相结合的方法,阐述三边交会和边角交会的基本原理,推导两者方法的坐标计算公式和精度评定模型,以济南市一条污水管线中的闸道变形观测为实例,进行方案设计、数据采集和成果分析.研究结果表明:采用TS30超高精度全站仪结合自由设站法,能够达到1~2 mm的精度,满足变形监测的精度要求.
In order to study the requirements of precision engineering measurement, the Leica TS30 ultra-high precision total station free standing station method is used to combine the theoretical analysis and engineering examples to explain the basic principles of the three-way rendezvous and corner rendezvous, Coordinate calculation formula and accuracy assessment model, taking a gateway deformation observation in a sewage pipeline in Jinan as an example, the program design, data acquisition and result analysis are carried out.The results show that: using TS30 ultra-precision total station combined with free standing station method , Can achieve the accuracy of 1 ~ 2 mm, to meet the accuracy requirements of deformation monitoring.
