上海地铁圆隧道中心轴线三维坐标测量
摘要:本文针对具体的测量精度要求，系统地介绍上海地铁一号线局部圆隧道中心轴线三维坐标测量的施测方法，计箅方法，并着重阐述了为达到精度要求而设计的具体方案，包括平面、髙程控制等级及观测要求、使用仪器等等，最后对实测成果作了必要的精度评定，并与设计值作了比较，得出事先的观测设计方案是切实可行的。
Abstract:The methods of construction survey of three dimensional coordinates, which is carried out in part of No.1 line of Shanghai subway for the central axial line of the circular tunnel, is systematically introduced as well as the computation of the coordinates. The emphasis is put upon the concrete plan which is designed according to the requirements of accuracy including the horizontal and level control orders, the observation requirements and the instruments used. The survey results are assessed in accuracy and compared with the designed values. It is concluded that the former plan of observation and design is feasible.
