叙述了全站仪用于隧道开挖施工中对围岩进行三维收敛变形测量的实施方法，其中包括：测量坐标系和基准点的建立；测点的布设要求；观测方法；观测精度以及空间边角网平差方法的介绍。结合北京地铁复线某车站地下施工现场所作的初步试验，进行了实际应用分析。
The implementation method of three-dimensional convergence deformation measurement of surrounding rock during the tunnel excavation construction by using total station is described, including the establishment of measuring coordinate system and reference point, the laying requirements of measuring point, the observation method, the observing accuracy and the spatial edge Introduction to the method of adjusting the angle network. Combined with the preliminary test of the underground construction site of a railway station in Beijing Metro, a practical application analysis was carried out.
