摘要

针对传统工程观测方法存在的基准点选取困难、自动化程度低及可靠性差等问题，设计了北斗Ⅲ高精度变形观测系统。为验证该系统在地表变形观测中的观测精度及应用效果，通过模拟试验分析观测精度与通视条件、定位时段的关系，并将上述观测系统与传统方法进行对比。结果表明，在试验区域内，保证通视条件且定位时段为 12∶00~16∶00 时，BDS-Ⅲ变形观测系统垂直向定位精度优于 1.5 mm，水平向定位精度优于 1 mm，相同条件下，水平向定位精度由于垂直向定位精度；该系统能很好的保证观测数据的完整性，得到的观测值与传统水准观测值基本一致，适合用于高精度、自动化地表变形观测工程。

Abstract

In view of the difficulty in selecting reference points， the low degree of automation and the poor reliability of the traditional engineering monitoring methods， a high-precision deformation moni- toring system based on Beidou III is designed. In order to verify the observation accuracy and applica- tion effect of the system in surface deformation monitoring， a simulation test was conducted to analyze the relationship between observation accuracy， viewing conditions， and positioning time. The moni- toring system is also compared with traditional methods. The results show that in the test area， the vertical positioning accuracy of BDS-III deformation monitoring system is better than 1.5 mm， the horizontal positioning accuracy is better than 1 mm， and the horizontal positioning accuracy is high than vertical positioning accuracy under the same conditions. The proposed system can guarantee the integrity of monitoring data， and the resulting observations are consistent with the observations from traditional leveling methods. The system is suitable for high-precision and automated surface deforma- tion monitoring projects.
