深基坑水平位移监测的自动测量及数据处理方法研究

Research on automatic measurement and data processing method for horizontal displacement monitoring of foundation pit

本文结合主流智能型全站仪的基本功能,提出了在深基坑水平位移监测中基于自由测站边角交会的自动测量方法,可有效提高外业测量的效率与数据质量,并对采集的数据进行平差计算与精度评定。通过工程实例的验证,证明该方法可满足一级深基坑的监测精度要求。

Combined with the basic functions of the mainstream intelligent total station, this paper proposes an automatic measurement method based on free-station in horizontal displacement monitoring of foundation pit which can improve the efficiency and data quality. The adjustment of the data collected is taken at the same time. Through real engineering examples, it proves that the method can meet the requirements of first grade deep foundation pit monitoring.
