全站仪自动化监测中的控制测量和坐标传递

Control Measurement and Coordinate Transfer in Automatic Monitoring of Total Station

在轨道交通运营线路采用的全站仪自动化监测方法中,常将测站设在变形区域内,因此需要实时解算测站点的坐标,判断解算所得的两期坐标是否精度相同、是否有必要采纳新的坐标值。由于隧道内空间狭小、且有限界要求,因此控制网布控的客观条件受到较大限制,有必要对一些控制测量方法在隧道内的应用进行实验分析。对隧道内采用的全站仪自动化监测方法所涉及的控制网设计、测站坐标传递与检验进行了论述。

In the automatic monitoring methods of total station used in the rail transit operation line,the measurement station is often located in the deformation area,so the coordinates of the measurement station need to be calculated in real time.At this time,it is often necessary to judge whether the accuracy of the two coordinates is the same and whether it is necessary to adopt new coordinate values?Due to the narrow space and limited requirements in the tunnel,the objective conditions of control network layout are greatly limited.It is necessary to carry out experimental analysis of the applications of some control measurement methods in the tunnel.In this paper,we discussed the control network design,the coordinate transfer and inspection of total station automatic monitoring method in tunnel.
