摘要
采用陀螺定向测量技术对隧道盾构施工中的洞内导线定向边坐标方位角进行检核。以实际的隧道盾构平面控制测量工作为例,介绍了洞内导线的布设与施测情况,并详细阐述了陀螺定向测量的流程、测量要求与取得的测量成果。最后将陀螺定向测量与导线测量成果进行对比,说明本次隧道盾构平面控制测量成果可靠,可应用在之后的施工工作中。
The gyro orientation technique is used to check the coordinate azimuth of the tunnel traverse directional edge in the tunnel shield construction.Taking the actual tunnel shield plane control survey work for example.Introducing the layout and measurement of the traverse in the tunnel.The process of measuring the gyro orientation,the measurement requirements and the measured results are described in detail.At last,the gyro directional measurement results are compared with the results of the traverse measurement,indicating that the tunnel shield plane control measurement results are reliable and can be applied in the subsequent construction work.
