摘要
针对地下空间精密测量中超长导线测量时存在的精度差问题,本文开展了一系列研究工作。首先,对地下空间超长导线测量的基本原理、测量难点、误差来源及改进方法等进行了系统性总结,为后续分析提供了理论依据;其次,针对地下空间超长导线测量的特点,设计了一套自动记录及平差软件;最后,在超长导线测量实验中对软件效果进行了应用。结果表明,所设计的自动记录及平差软件规避了人为误差影响,引入了独立的陀螺方位角约束优化平差模型,在精度控制、成果可靠性等方面有显著改善,不仅为地下空间建设提供了测量方法,还为地下空间测量技术的发展积累了宝贵经验。
A series of research has been conducted to address the accuracy issues in ultra-long traverse surveying in precise surveying and mapping in underground space.Firstly,a systematic summary of the basic principles,surveying difficulties,error sources,and improved methods of the mentioned surveying in underground space have been provided,so to lay a theoretical foundation for subsquent analyzing.Secondly,a set of total station recording and adjustment software has been designed based on the characteristics of ultra-long traverse surveying in underground space,and applied in ultra-long traverse surveying experiments.It is concluded from comparative verification of the surveyed data that the designed software has no human intervention errors,it introduces independent gyro-based azimuth control in survey network adjustment,and so enable the great improvement of both accuracy and reliability.The study not only provides surveying methods for underground space construction,but also accumulates valuable experience for the development of underground space surveying technology.
