摘要
该文通过11台全站仪在固定基线上进行收敛测量的比对试验,结合观测精度进行分析,得出全站仪无棱镜测距能满足隧道收敛测量精度要求的结论,并对保证收敛测量成果质量提出了校准,以及修正全站仪加常数、多测回观测等建议。
Through the comparison test of 11 total stations to carry out the convergence measurement in the fixed baseline and according to the accuracy of observation, the article analyzes and gives the conclusion of the non-prism leveling distance of total station able to satisfy the convergence measurement precision of tunnel, and puts forward the proposals of checking and revising the constant and the multiple observation of the total station in order to guarantee the quality of convergence measurement result.
