全站仪边角后方交会在水平位移监测中的应用

The application of the drawing in horizontal displacement monitoring after the corner of the whole station

分析常规水平位移监测方法的缺点,提出了一种基于全站仪边角后方交会法在水平位移监测中的应用,并阐述了该方法的原理及其误差构成。随后,以某桥梁位移监测为例,介绍了该方法在城市复杂环境下的应用。结果表明,运用该方法解决了基准点选埋困难,工作基点稳定性联测难度大,基准点稳定性不易保证的问题。

By analyzing the shortcomings of the conventional horizontal displacement monitoring method, this paper proposes a method based on total station edge-cross intersection method for horizontal displacement monitoring, and expounds the principle of the method and its error composition. Taking a bridge displacement monitoring as an example, this paper introduces the application of this method in urban complex environment. The results show that this method solves the problems of difficulty in selecting and embedding base points, difficulty in joint determination of stability of working base points, and difficulty in guaranteeing the stability of reference points.
